Great tutorial darrengladysz, very thorough and concise!

I had a bit of a problem though with partitioning my main SanDisk 16GB card. For some reason Easeus Partition Master wouldn't allow me to resize/delete it. I did a little browsing and came across this solution which works perfectly.

"Steve wrote:
How do I delete a partiion on a micro SD card when it is plugged into an XP
machine on USB?

No way without 3rd party tools. Windows sees the card
reader as drive with a removable media and here partitioning
is not supported. If multiple partitions are present then
only the first one is mounted.

A complete erase of the card can be done by my DiskErase tool:

If you format it afterwards in a digicam, then you will
get one single partition. If you format it under XP then
you get a "super floppy" (no partition table).

Maybe the "EASEUS Partition Master" can deal with partitions
on removable drives (I've never tried):

Or turn the cardreader into a "fixed" drive, then partitioning
is supported by XP:

Uwe"

I downloaded the Disk Erase tool and set it to erase my 16 GB card though it did take a very long hour or two it did the job and removed the partition. Now I'm off to mess around with it!

P.S. Sorry I can't link the app because of the new user limitation. I tried attaching it to this post let's see if it works

i think not all Android builds are supported... what build were you using ?


I tried booting the NexusHD2-FRG83D V1.8 build and it froze on start up. I tried it about 5 times, so I guess that one doesn't work.

Damn...

If you have a small wp7 partition and transfer this to your larger sd card it should not affect anything as wp7 will boot from this partition and you will not need to reflash the wp7 rom.

If you have to re-create the partitions using the procedure above then yes, you will need to reflash wp7 and reconnect to live services as there is no know way to reduce and/or resize the wp7 sd partition.

BTW I have reconnected 4 times so far to live services and have had no problems.

Regards,

thanks for the reply, I think its an sd card issue, my card looks exactly like yours the only difference is the name of the card, which I assume doesn't make a difference

Thanks this is a great tutorial

My findings

I've since done this several times and have been trying to find different quicker ways (there doesn't seem to be one). Some notes.
1) You don't seem to be able to make any pre-partitioning schemes to the card pre wp7 install (tried ext2, 3, 4, exfat, etc) as it WILL be over-written.
2) You can't resize the WP7 partition after its been created, it changes the software raid FS that WP7 uses
3) This takes a VERY long time, please be patient.
4) I activated my live services AFTER I copied the file systems. I ended up creating a copy in VFS for backup once I was done. Hopefully this process will be easier in the future.

Thanks for the tut for dual booting. I got WP7 working good so far, however my attempts at loading Android from SD (specifically the build you mentioned in your post) is stuck on the htc loading screen.

I know you mentioned it takes long to load in your tutorial, but it's been a good 30 - 40 minutes on my second try now and it's still there. Is that the amount of time you had to wait for it to load? Or is it longer? Can you please let me know.

I didn't place it on the SD card in the "Android" folder - should I have done this? I placed it in there as "desire_z" and choose that directly for loading Android in MAGLDR.

Thanks again

P.S. I pm'd you too but thought it would be good to put this out in the open in case anybody else is experiencing the same problems

I also had issues with freezing and found it took long. I added a step that helped me with speed (see revised 1st post - New step 8a). Basically reformat the fat32 partition with 32 or 64 kb sectors while still in windows. I used 64 kb.

Each build has its own folder. I used desire_z as this was the instruction for this particular build.

Oh I see. I'll try that out and report back with my results. Did you see a considerable amount of improvement with this fix? And if you don't mind me asking how long does it take for you to load the build?

Thanks for the quick reply

I May Have Found A Way To Partition Using ONE CARD, Keeping The WP7 Data Intact, Activation Intact And Still Having The Ability To Run Android. Copying Over Files Right Now, About To Fully Test ... Will Report Back.

UPDATE : After Partitioning ONE CARD, WP7 Boots Normal - If Already Activated, You Lose Activation On Partition Reboot. MAGLDR Recognizes Partitions, And Setting Android Folder Works, As For Android : MATTC FROYO 1.5b Tested ... Starts Up But No Dice. After Loading To Lockscreen, It Shuts Itself Down.

Time to install was about 15 minutes give or take a few. Speed and stability much enhanced by this.

BTW this was a trick used with sd android builds. The idea is that using 64kb sectors requires less trips than 16 or 32 kb sectors.

I may try some other builds later and will include in 1st post.

IF ANYONE HAS SUCCESS WITH OTHER BUILDS, PLEASE LET ME KNOW. THANKS

Sounds good R2HD2, keep us posted! Though for those of us who have already foregone transplanting the two sd cards this might not be of much use it might help a bunch of other people lol

Does anyone know how to hard rest after flashing Wm7 since I am experiencing constant freezing and reboots?
(I read that hard reset might solve this problem)

thanks

15 minutes hey that's not too bad. I'll keep a timer running hopefully it works this time around thanks.

If this works out I'm thinking of trying the SuperRam build by darkstone/killahurtz. I took a plunge and wanted to see if I could accomplish nand WP7 and a PSfreedom compatible Android booting from SD

You'll definitely be the first to know if it succeeds

    TUTORIAL:

    You can have Wp7 and android at the same time. You will have Wp7 in Nand and run android from the same sd card or another sd card that you will swap when you want to run Android from sd. You can't run wp7 and android from Nand at the same time however.


    HOW TO PARTITION YOUR SD CARD TO HAVE A DUAL BOOT OF WINDOWS PHONE 7 AND SD ANDROID

    The purpose of this tutorial is to detail a method on how to get wp7 and sd android sharing the same sd card. At present, if you want to have Wp7 in nand and android on the sd, you will have 2 choices. A. swap sd cards or B. Partition your sd cards as detailed hereafter. IMO partition the sd card as detailed hereafter is the safest route for a dual boot from the same sd card (instead of swapping sd cards) as wp7 will ruin an android sd card inadvertently left in the phone.

    Wp7 uses a special format for its sd card and you cannot simply copy android on this partition as it is not accessible. Wp7 also creates a fat32 partition of 200 mb but this partition is too small to install an android build. I am not aware of any means to resize the Wp7 partition on the sd card either.

    This is based on ike2903’s instructions and all credits go to him as well as to others on xda. I am not a developer and guess just got lucky getting things to work.

    Note to moderators, if this post is in the wrong area, please move it to the correct one. Thanks.

    METHOD ONE - USING TWO SD CARDS

    WHAT YOU NEED:

    1. TWO sd cards.

    A large one and a smaller one. I am using a 8gb and a 16gb card. The larger one will be your permanent sd card and the smaller one will enable you to obtain a smaller partition to run wp7 that you will copy to the larger sd card.

    2. Sd partition software.

    I used EASEUS ALL-IN-ONE Partition Manager Software and it worked. It is free to download and here is the link: http://www.partition-tool.com/download.htm

    INSTRUCTIONS

    1. Download and install Easeus Partition Manager.

    2. Insert your small sd card into your phone. Flash WP7 Rom using Magldr 1.1.2. Let the phone reset and start wp7. This will allow WP7 to format your smaller sd card with its partition.

    3. Turn off your phone and remove the smaller sd card.

    4. Plug in both sd cards in your pc. The larger and the smaller one.

    5. Run Easeus Partition Manager. You should see both the smaller and larger sd cards. On your smaller sd card, there should be 2 partitions. A fat 16 partition of 200 mb and another partition called unformatted which takes up the rest of the smaller sd. This “unformatted partition” is actually your wp7 partition. See attached picture.

    6. Delete the partition of your larger sd card. To do this, select the partition and right click delete (menu also works). Don’t forget to click “apply”.

    7. Copy and resize the fat16 partition of your smaller sd card to your larger sd card. To do this, select the partition on your smaller sd card, right click (or use the menu) and select copy and follow the onscreen wizard to copy. You can change it to fat32 as well. When resizing, you need to do some math. Take the size of your larger sd card and subtract the size of the “unformatted” partition of on your smaller sd card and set this value as the resize value for the fat16 partition that you are copying. In other words, if the unformatted partition is 8gh and you are setting things up on a 16gb sd card then set the resize value to approx. 8gb. Click “apply”

    8. Using same procedure as outlined in 7, copy the “unformatted” partition from your smaller sd card to the larger sd card. Click “apply”.

    NEW STEP: Before copying your android build and while still in windows format the fat 32 partition using 32 or 64 kb sectors USE WINDOWS EXPLORER OR MY COMPUTER TO FORMAT. This should help with speed. I used 64 kb sectors. I am using the desire_Z build in this post and set up everything in the desire_z folder

    9. Copy your android sd build onto the fat32 partition. IMPORTANT - Do not use usb mass storage as there is some data corruption problems. Remove your sd card to copy (see below and thread for list of working builds - IMPORTANT you need to have a modified rootfs.img file where nand_init was added to init.rc and you need to copy and replace the existing rootfs.img file of the sd build else it won't work)

    10. Remove the larger sd card and insert it into your phone.

    11. Reboot the phone and hold the “red end key” to enter the magldr boot menu.

    12. In Magldr 1.1.2 use volume down to go to “9. Services” and click “green phone button” to select.

    13. Use volume buttons to select “1. Bootsettings” and click “green phone button” to select.

    14. Use volume buttons to select “2. Always Menu” and click “green phone button” to select. This will give you the Madldr menu on phone startup to allow you to choose wp7 or sd android as your boot choice.

    15. Click the “green phone button” to confirm.

    16. Once you’ve done steps 12 to 15 you will be brought back to the initial magldr 1.1.2 menu.

    17. Again, use volume down to go to “9. Services” and click “green phone button” to select.

    18. Use volume buttons to select “1. Bootsettings” and click “green phone button” to select.

    19. Use volume buttons to select “3. AD SD Dir” and click “green phone button” to select.

    20. Select the folder where your sd android build is located.

    21. Reset your phone and enter Magldr 1.1.2.

    22. To boot into wp7 select boot “1. Boot WPH” or to boot sd android select “2. Boot SD AD”

    23. Booting into android sd is long. Guess having android nand has spoiled us.

    SECOND METHOD - USING A SINGLE SD CARD

    Here is an alternate method provided by gencaslan to do this:

    http://xdaforums.com/showpost.php?p=10643011&postcount=64

    THIRD METHOD - USING A SINGLE SD CARD - HERE IS ANOTHER ALTERNATE METHOD PROPOSED BY XDA MEMBER HYELLOW (UPDATED)

    1. Put your sd card inside the hd2 and power on.

    2. Go to about screen, in settings, and reset your device. Let it reset and boot to WP7 again. While booting to WP7, it'll create the partitions it needs, so this is important. After you have gone through the setup wizard, go to about screen and reset your device again.

    3. When it has booted into magldr screen, remove the sd card and insert into pc. (make sure that magldr is shown and stays there at bootup, otherwise it'll boot straight into wp7 without sd card and that is not what we want.

    4. You'll see two partitions. A whopping 200mb of fat16 partition and the other is unformatted. Now right click on the unformatted partition and click delete. After that, click apply. Now you have unallocated space. Right click on the unallocated space and select create. Set parameters to logical and unformatted and size the partition. This will be your WP7 partition, so decide how much you want to allocate to it, this is permanent, no changes afterwards can be made. Also, make sure you move it to the end of the sd card in the same 'create' window. Hit apply. IMPORTANT When using this method make sure that the wp7 "unformatted partition" is larger than the Android partition otherwise the wp7 "unformatted partition" will move in 2nd place and you will not be able to resize the fat 16 / android partition.


    5. Sit back and take a break.

    break.

    6. You now have a green fat16 partition to the left, some unallocated grey portion in the middle and your WP7 partition in modern turqoise colour on the far right. Agreed? Now remove the sd card from PC and insert in HD2.

    7. After you have inserted the sd card, let it boot into WP7. Remember what your last action was when you were still in WP7? Yes, you pressed reset, so the device actually thinks he is still resetting the device. He might do it too, but just go through the setup wizard again.

    8. Go to about screen and verify your storage. Don't look strange if when the storage has a different of about 1Gb, this is swallowed by WP7 for system stuff etc. Are you happy with the progress so far? Then power down your device and remove the sd card. Allow the HD2 to fully powered down as sometimes the screen is pitch black, but the device is still turning off.

    9. Insert the sd card in pc and, using EASUS right click on the green fat 16 partition and select resize/move. Now fill up the rest of the unallocated space and hit apply. This is your android partition.

    10. Format the sd android partition (not the whole sd card!) using EASUS to FAT32 using 32 or 64 kb cluster size and put an android build onto it and test.

    11. IMPORTANT You need to convert the wp7 unformatted partition to primary for the sd android to see the sd card Use minitool partition wizard to do this. Right click on your WP7 unformatted partition and select modify and then click on set as primary and hit apply. Here is the link for minitool: http://xdaforums.com/showpost.php?p=10887494&postcount=372

    HERE IS A 2 CARD METHOD POSTED BY NZXTNEO

    (I created a 4gb WP7 build and allocated the rest to Android)

    Copy everything in this vid exactly!
    http://www.youtube.com/watch?v=JTHRAUHZHlo
    (I used an 8gb SD card for this step)
    Then connect the 8gb SD and a 16gb SD to a computer via card readers. (Yes this will be a 2 SD card process)
    Open EASEUS Partition Master
    Delete any partitions on the 16gb SD so that it reads as unallocated
    Hit apply
    Right click the unformatted partition of the 8gb SD and select copy
    Move the unformatted partition to the larger unallocated SD card
    Drag the 4gb partition all the way to the right
    Hit apply
    (Please note the move step will take a long time)

    The unallocated partition is now ready for you to format for use with Android

    VIDEO INSTRUCTIONS


    Geolo has made a nice video tutorial and posted it on youtube. Here is the link: http://www.youtube.com/watch?v=o0YI-SV4KiU

    Here is another video by Geolo for persons with only 1 card and 1 card reader. Here is the link: http://www.youtube.com/watch?v=N-cUdB4_5f4


    NOTES:

    Make sure you backup your sd cards as wp7 will erase all that is on them.

    This method works for me but i take no responsibility for whatever may happen to your phone.

    You should be able to reactivate your phone with windows market but I cannot guarantee this. I have re-activated market 4 times so far.

    TESTED SD BUILDS:

    Most builds should work but you will need an edited rootfs.img file for it to work. Have a look in the thread of the build you want if someone posted an edited rootfs.img file.

    You can get a list of edited rootfs.img files here:

    3in1 [WPH7 + ICS SD + ICS NativeSD] on Your HTC LEO​
    This method based on Geolo with my modifications
    Device requiments:
    • HTC LEO (HD2)
    • Card reader with support microSD
    • 2 microSD cards - 2Gb for WindowsPhone 7 & 8Gb (or higher) for Android builds
    • USB cable (miniUSB Device-PC)
    • PC with installed Microsoft Windows XP/Vista/Se7en (32/64)
    Software requiments (HD2):
    Software requiments (PC):
    Time requiments:
    • 1.5-2 hours for 1 card reader and mass storage mode on your phone
      or 20-40 minutes for 2 card readers (all partition operations without HD2)
    Difficultly level:
    • Advanced users (you may optimize any steps of this guide at your risk)
    • Beginner users (with basic knowledges of Windows (PC & Mobile editions), Android & Partitions), just do it step-by-step

    So, if you are agree previous requiments and ready to begin - lets do it now

    Step1. Prepare your sdcards
    • Insert your bigger (8Gb or higher) sdcard into card reader and connect it to your PC
    • MAKE FULL BACKUP ALL CARD DATA
    • Run Panasonic SDFormatter and begin format your sdcard as Full Erase mode
    • Done. Change your bigger (8Gb) sdcard to smaller (2Gb) sdcard and reconnect card reader to PC
    • MAKE FULL BACKUP ALL CARD DATA
    • No formatt req. because WP7 will do this for you at install & 1st start
    • Done!
    Step2. Install & setup WP7
    • Now, put your smaller sdcard in HD2 and turn it on
    • Choose 5th menu USB Flasher. Connect your HD2 to PC and execute install app (in my chooce, I'm used DAF.EXE (any other binary installer) app from HD2O© WMP7 Tango ROM)
    • Wait until the install process of WP7 to your HD2
    • Done! Device will rebooted automaticly
    • In MAGLDR choose 1st menu Boot WHP and WP7 will be booted
    • Complete stup your WP7 (language, time zone, date, time etc.) IT IS VERY IMPORTANT!
    • After complete setup, turn off your HD2. Do not reset setting to default from About menu! IT IS VERY IMPORTANT!
    Step3. Partitions Task #1
    • Turn on your HD2 with smaller sdcard (2Gb/WP7)
    • In MAGLDR choose 4th menu USB MassStg and connect your HD to your PC
    • Insert your bigger (8Gb or higher) sdcard into card reader and connect it to your PC
    • Run EASEUS Partition Master. Now you can see your both sdcards, like this:
      Disk X (smaller sdcard 2GB/WP7)
      ** FAT16 200MB Primary
      ** Unformatted 1.65GB Primary
      Disk Y (bigger sdcard 8GB)
      ** FAT32 7.28GB Primary
    • Resize existing FAT32 partition on bigger sdcard by this calculate:
      ** For WP7 we need 2GB (2048MB)
      ** Other avaible space for Android builds
    • Press Apply. Now you have this:
      Disk Y (bigger sdcard 8GB)
      ** FAT32 5.28GB Primary
      ** Unallocated 2.01GB Logical
    • Copy 200MB FAT16 partition (on smaller sdcard) and paste it to Unallocated space of bigger sdcard
    • Press Apply. Now you have this:
      Disk Y (bigger sdcard 8GB)
      ** FAT32 5.28GB Primary
      ** FAT16 191.11MB Primary
      ** Unallocated 1.82GB Logical
    • Copy 1.65GB Unformatted partition (on smaller sdcard) and paste it to Unallocated space of bigger sdcard
    • Press Apply. Now you have this:
      ** FAT32 5.28GB Primary
      ** FAT16 191.11MB Primary
      ** Unformatted 1.65GB Primary
      ** Unallocated 1.82GB Logical
    • Check up partitions order:
      FAT32 -> FAT16 -> Unformatted -> Unallocated
      Where FAT32 (is your partition for Android builds SD & NativeSD), FAT16 & Unformatted (is your partitions by WP7)
    • Done!
    • Discinnect both sdcards, turn off phone and put in bigger sdcard
    Step4. Reconfigure WP7 & accept new sdcard
    • Turn on HD2 and start WP7 from MAGLDR by 1st menu Boot WPH
    • WP7 must be start and accepted your new sdcard with old (from smaller sdcard) partitions (FAT16 200MB and Unformatted 1.65GB)
    • Check it by App menu -> Settings -> About
      See attached screenshot
      If system shows Total Storage: 1.64GB and Avaible storage: 1.34GB you are man :laugh:
      Else, you make mistakes while making/copy partitions in 3rd step. Anyway, you can see video and check it again
    • Turn off your HD2
      :D
    Step5. Partitions Task #2
    • Replace bigger sdcard from HD2 and put it in card reader because we will work with partitions on this card
    • Connect card reader to PC and run MiniTool Partition Wizard
    • Now select 1st partition of sdcard (FAT32 5.28GB Primary) and resize it with next calculate:
      50% of size for Android SD builds and 50% for Android NativeSD builds
      But you choose your own size for your Android as you want
    • Press Apply. Now you have this:
      Disk Y (bigger sdcard 8GB)
      ** FAT32 2.61GB Primary
      ** Unallocated 2.67GB Logical
      ** Unknown 191.11MB Primary
      ** Unknown 1.65GB Primary
      ** Unallocated 1.82GB Logical
    • Select Unallocaed (red) and choose Create New partition
    • Choose type Primary and system Ext4, then press OK
    • Press Apply. Now you have this:
      Disk Y (bigger sdcard 8GB)
      ** FAT32 2.61GB Primary
      ** Ext4 2.67GB Primary
      ** Unknown 191.11MB Primary
      ** Unknown 1.65GB Primary
      ** Unallocated 182MB Logical
    Step6. Final
    • Now you have 1 device HTC LEO (HD2) with:
      - NAND partiotion with Windows Phone 7
      - FAT32 partition for Android SD/MAGLDR builds
      - EXT4 partition for Android NativeSD build
    • Are you happy? no? read this thread again :D
    If you can not understand step-by-step guide, see my video where I'm do it step-be-step specially for you :)

    UPDATE :

    you don't really need dd if you don't need backup.

    1. install wp7 nand with the smaller card inside.
    2. put the bigger card in the phone and the smaller card in your card-reader. select mass storage mode and copy the unallocated partition over from the smaller card to the bigger cards end with the partition manager.
    3. create a fat32 partition at the beginning of the bigger card.

    done

    ...

    Preparation :

    Download command-line tool dd from http://www.chrysocome.net/dd and extract to a folder on your computer C:\dd-0.6beta3

    Download the partition manager from http://www.partition-tool.com/download.htm and install.


    1. Flash WP7 with smaller sd-card mounted in your mobile device. (about 10 - 20 minutes)

    2. make an image of your sd.

    Open a Console
    XP : Start -> Execute -> cmd.exe .
    Win7 : Start -> Enter in Searchfield -> cmd.exe

    change to the folder where dd was extracted to


    mount the sd-card in an (usb) sd-adapter. the command is described in http://www.chrysocome.net/dd "Read the entire USB memory device" BUT use at least bs=4M as block size if you use 1M it will take hours. (about 5 -10 mins)
    you can try greater values as 4M as the usb2-standard allows up to 30M per second (see http://www.everythingusb.com/usb2/faq.htm#4). 8M is optimum for me.
    C:\dd-0.6beta3>dd if=\\?\Device\Harddisk1\Partition0 of=c:\dd-0.6beta3\usb2.img bs=8M --size --progress

    3. write image to bigger card. put bigger card in the (usb) sd-adapter and execute the following command. (about 5 -10 minutes)
    C:\dd-0.6beta3>dd of=\\?\Device\Harddisk1\Partition0 if=c:\dd-0.6beta3\usb2.img bs=8M --size --progress

    4. use the partiotion manager to copy the wp7 partition to the unallocated space at the end of the bigger sd-card. make it NOT primary. ( 20 - 30 minutes)

    5. delete the 200MB fat16 and the first wp7 partition. (few seconds)

    6. create fat32 partition with the partition tool on the unallocated space . select it as primary. (few seconds)

    credits to all uf us.

    you can skip step one if you did an image once. so the whole process takes about an hour. also you can use the image-file as backup if you mess around with wp7 or ruin your card or something. just copy back the image on a new card.

    Take a look at Fmstrats usefull tips.

    when it says you can run android and windows phone 7 off the memory card does that mean you can have windows 6.5 as well without the memory card
    No, WP7 takes up the NAND space, and you can boot Android from SD with magldr. Cotulla is working on a SD version of WM65 though, so if he successfully creates that, we will be able to boot WP7 from NAND and WM65 and Android from SD.

    i did the partitioning successfully (8gb sandisk), but my android can only read the data.img (1gb) space as internal one & cant find the rest of the space as sd card (3gb) (it says there's no sd card inserted)
    hlep pleaz:confused:
    You have to use minitool partition manager to change your wp7 partition from logical to primary... then your android build will be able to mount your sd card successfully. I attached it for you.

    That's dope that there's these videos to help out people, but id like to see one showing how to do it with the alternate method with 1 card.. Mostly to see if peeps are even telling the truth saying its possible.. Like I said earlier, couldn't do it with that method, ended up having to do with two cards, 1 8gb card and 1 16gb for 8 per OS :[ (wanted majority for Zune music, but no dice)

    Sent from my htc HD2/7 using Board Express

    I am doing it with one sd card whole the time. Can't see why it is so hard to believe. If you are not able to do it following a very simple guide, then even I can not help you further.
    I have a 32gb sdcard that I tortured on the day it arrived, not knowing if I could make it happen or would destroy the card forever. First time i followed the tutorial using 2 sd cards and later I found en easier way, by accident though.
    Sure there might be someone able to make a video, but with all the help from other members, I don't think it can be that difficult to achieve the same, what I and others have done. I can however, explain it to you again, just let us know.

    Ok, I am going to putt it down again for you and others that are still having problems to do it.

    1. Put your sd card inside the hd2 and power on.
    2. Go to about screen, in settings, and reset your device. Let it reset and boot to WP7 again. While booting to WP7, it'll create the partitions it needs, so this is important. After you have gone through the setup wizard, go to about screen and reset your device again.
    3. When it has booted into magldr screen, remove the sd card and insert into pc. (make sure that magldr is shown and stays there at bootup, otherwise it'll boot straight into wp7 without sd card and that is not what we want.
    4. You'll see two partitions. A whopping 200mb of fat16 partition and the other is unformatted. Now right click on the unformatted partition and click delete. After that, click apply. Now you have unallocated space. Right click on the unallocated space and select create. Set parameters to logical and unformatted and size size the partition. This will be your WP7 partition, so decide how much you want to allocate to it, this is permanent, no changes afterwards can be made. Also, make sure you move it to the end of the sd card in the same 'create' window. Hit apply.
    5. Sit back and take a break.

    break.

    6. You now have a green fat16 partition to the left, some unallocated grey portion in the middle and your WP7 partition in modern turqoise colour on the far right. Agreed? Now remove the sd card from PC and insert in HD2.
    7. After you have inserted the sd card, let it boot into WP7. Remember what your last action was when you were still in WP7? Yes, you pressed reset, so the device actually thinks he is still resetting the device. He might do it too, but just go through the setup wizard again.
    8. Go to about screen and verify your storage. Don't look strange if when the storage has a different of about 1Gb, this is swallowed by WP7 for system stuff etc. Are you happy with the progress so far? Then power down your device and remove the sd card. Allow the HD2 to fully powered down as sometimes the screen is pitch black, but the device is still turning off.
    9. Insert the sd card in pc and right click on the green fat 16 partition and select resize/move. Now fill up the rest of the unallocated space and hit apply. This is your android partition. Put an android build onto it and test.
    10. If you want to convert your WP7 partition from logical to primary, please search in this thread for the the program: minitool partition wizard.
    Right click on your WP7 partition and, select modify and then click on set as primary and hit apply.

    That's it.
