Triple Boot WP7+SD+NativeSD EXT4 @ 1 SD with pictures

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**

after that is done the partitioning begins

• 1 FAT32 Partition
• 1 EXT4 Partition
• 1 WP7 Partition
• MiniTool Partition Wizard Home Edition (MTPW) using this to do those above.

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! :cyclops:

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

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 :fingers-crossed:


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! :highfive:

for partitioning I followed This

YIKES!!!
that's what I was afraid of, that's why I made BIG & Clear, well actually it happened to me once a long long time ago

Anyways there are powerful partition recovery out there, I hope you get it back.

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 :cyclops:

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

@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

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

here's one's posters take on about SD speeds

Because Class 2 and 4 have better random access speed than an Class 6 or Class 10! Class 2 or 4 was the better choice for an OS, Class 6 or 10 was the better choice for big datas like movies or pictures, because they have a cache! This cache (Class 6/10) must always rebuild and this make it very slow for random access.

Also sorry for my bad english.

I am using a class 10 16g Sandisk & it seems to run well though I wish I had a 32gig

@soulforger
good to know you got your files back! :highfive:
let us know how it goes with those cards.

@derschnelle
2.15.50.14 is good for all, once you flash this radio from the start you can leave it alone with WP7 or Andy. One Radio to rule them all :cyclops:

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?
