[HD2 General] mengfei:
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:
