​

In this thread I have put together a tutorial on how to dual boot WP7 and Android using the one card method. To use Android, the build must be one that has been adapted to work via Magldr. Builds which has been kindly adapted by zarathustrax are on Post 2 so please show your thanks to him for taking time to convert them for us to use.

This tutorial presumes you already know your way around Magldr and know what buttons to press to select etc. If you need any help then let me know. I will help the best I can but cant always promise to be online. The tutorial recommends you use a SD card reader instead of Mass Storage in Magldr as Mass Storage is not always reliable.

1/ Download a WP7 and Android Build (Maglrd Build) you want to use.

2/ Run DWI.exe to install WP7 to your phone.

3/ Go through the setup and once it tells you that you have a new SMS which is welcoming you to WP7 go to Settings - About - Reset Your Phone and once phone restarts hold power to enter into Magldr.

4/ Remove SD card and insert it into the computer.

5/ I used Minitools Partition Wizard which you can get HERE, the Home version is free. Start the program and you will see two partitions on your SD card. Right click and delete the largest partition, this will leave you with Unallocated partition.

6/ Now right click the Unallocated partition and select Create. Leave 'Create As' as Logical and 'File System' as Unformatted. Under 'Size and Location', slide your Unallocated space to the right to roughly half the size of your SD card so the blank grey area is on the left. Click OK.

7/ Now click on Apply (The tick) and when it comes up saying Successful (This may take a while), remove your SD card and put it back into your phone and shut down Partition Manager.

8/ Boot up WP7 and go through the setup again. Once the message beeps again to say welcome to WP7, go to Settings - About and look at the 'Total Storage' and 'Available Storage'. These values should now be roughly the same.

9/ Hold Power button to restart and hold Power to enter into Magldr. Remove SD card and put it back in your card reader. Open Partition Wizard again, right click on the 200MB Other partition and select Delete. Right click on the new Unallocated partition and select Create. The File System should be Fat32 and set as Primary. Click Ok and Apply (The tick).

10/ When all the changes has been applied click OK and right click on the Other partition and select Modify and then Set Partition As Primary. This is important to run Android as well as WP7. If Partition were still Logical then once Android Build was loaded it would not recognise anything off your memory card . Put the SD card back into your phone and boot WP7 and exit Partition Manager.

11/ In WP7, go to Settings - About and double check the Total Storage and Available Storage to see if they are the same as before, they should be except the one should now be 200mb larger.

12/ Power off and insert SD card back into your card reader.

13/ This time start Computer or My Computer depending what version of Windows you are running. Move the Android Magldr folder to your SD card and read the instructions to set boot settings in Magldr. This time I will Boot MarkinXHDExtraClean Magldr Build but DL Desire Magldr build worked for me just as good as Nand. You can also use one of the builds in Post 2.

14/ Once Android folder has been copied, remove the SD card and put it back into your phone. When in Magldr, press the volume buttons up and down until you get to Services - BootSettings - AD SD Dir. For MarkinuXHDExtraClean Build the zImage and initrd.gz are on the main directory of the SD card so select <->. Always read the chefs installation instructions.

15/ You should now be in the main Magldr menu. Press vol buttons and select Boot AD SD.

Congratulations.......you know have WP7 and Android dual booting on your device. If this tutorial helped you, then please hit the Thanks button.
