Lets try to triple Boot our HD2's with WIN7 + SD + Native SD via Magldr, although I got mine working OK, i'm not entirely sure if this is viable to all. please see last part.

I assume you already have Magldr in your HD2 & its either running WP7 or Andy in NAND or already dual Boots.

If not flash WP7 first in NAND by trying to follow this, WP7 is always in NAND **Anything you have in NAND/ SD will be deleted including CWM**
http://forum.xda-developers.com/show...5#post25781675

after that is done the partitioning begins
Be very careful when using the minitool partition as you can accidentally format/ delete your Hard Disk Partition.

i'll be using a 16g card & after flashing WP7 it uses the SD Card as it's own storage using it's own format similar to a RAID setup making it like an Internal storage & what's left is usually 200mb of free space. We need to take back some of that space!

A - Set Magldr > Service > Boot Setting > Always Menu

After you reboot & setup WP7 go to:
••settings > about > reset your phone > YES! > phone re-boots



since you set A your still in magldr (don't let it boot to WP7 - yet), remove the card, put it in your PC & run MTPW

you will see something like this



right click on the larger (other)(14.64GB) partition & choose delete
right click on the larger (now unallocated)(14.64GB) partition & choose create partition as "Logical" with "Unformatted" file system.
Slide the tab to the Right leaving a partition slightly larger than 1/2 the SD card that was shown in MTPW
Make sure the "Unallocated Space After : is ZERO 0



after pressing OK something like below will show
Noticed that the "Unformatted" is larger than the "Unallocated" partition
click "Apply" & wait for it to finish.



••Close MTPW > insert SD card to HD2 > Boot WPH
WP7 will continue to boot & do the usual setup stuff
settings > about > to see if the partition has changed.



Turn OFF the phone, take out the SD card & plug it in the PC then run MTPW
the "Unformatted" before now becomes "other" to MTPW which WP7 formatted for it's own use.



right click on the 200MB "other" partition & delete it!
noticed that it combined with the "unallocated" partition & now we have just 2 partitions



right click on the "unallocated" partition
Create As > Primary > FAT32
slide the Tab to the Left for the EXT4 partition, i choose around 2g



when you press OK, an allocated space will be there
right click on the "unallocated" partition
Create As > Primary > EXT4



right click on the "Other" partition
Modify > Set partition as Primary



Now we have 3 Primary Partitions, click Apply & when all is done your ready to go!


copy all the necessary files you need to the SD & see if WP7 boots First, see more on NativeSD+EXT4 below
NativeSD Rom+EXT4 for New Users with peechurs


Error Message
when i ran EXT4 recovery there was an error message & it does not boot to TWRP (touch), although with this error message all seems to be running ok - for now


Many thanks to the Dev's & Guys that gave us so much for our HD2, don't forget to hit the "Thanks" button for our guys!

Man this is a pretty good guide, it is also needed to as Native SD is still new to the HD2. I am glad to see you can use 4EXT with the HD2 now as I feel it is truly the best custom recovery out at the current time. I absolutely love the 4EXT recovery Control app, it is the paid version but you can also get the 4EXT Updater app which is free but not all the features are available in it. I am going to suggest this guide for the Portal as it proves you can multiboot OS using Native SD. Thanks for taking time to write this up mengfei.

thanks Man!

I just extended the dual boot of WP+SD to include EXT4 & i hope it's helpful to those that want to have as much option as they can have. I now have like 10 roms just in case one goes bonkers, what a Paranoid hehehe

BTW here's Xylograph's reply to the error I was getting.

so i guess it's not that serious

Thumbs up
wonderful tutorial in very easy language... I am sure one does not need to scroll up-down too many times to see the steps...

I have been away from WP7 for a long time but would like to taste it once again :P

Hi mengfei, do you expierence poor speed performance on android with triple boot? I installed NexusHD2 rom with nativesd and, I must say, it is painfully slow and barely usable. Even downloading something to the card is slow. I have no speed problem with wp7. I have a transcend 8gb class 6 with this partition layout: 2,5Gb Fat32, 1,5 EXT4, 3gb for wp7. Is there something I can check or I can do to improve my android installation or the speed of sdcard?

@serverless
no problem with my 16g Sandisk Class 10, just flashed JB AOKP's latest & it's buttery smooth.

I had problems with a 4g Sandisk which i think had a problem or is fake even when running normal SD Rom's & my Class 10 16g Transcent is not compatible with WP7 - it wont detect it.

if you can try another Card or reformat the card, give it shot.
HTH

Yes, it is very good. though I now feel that I need to change my SD card. I have an 8 GB Class 2 SD card (the main culprit for slow speed) and now I am thinking to buy a 16/32 GB SD card but confuse with the class. I know Android write data on non-sequential manner but which one would be better? I am thinking of buying either Class 4, 6 and 10 SD card.

Thanks
