With MAGLDR, a program created by the Dark Forces Team (DFT), being released and Windows Phone 7 running fine on the HD2, we’re now able to dualboot Android and Windows Phone 7. Following this tutorial by XDA member darrengladysz will ultimately result in being able to select either WP7 or Android from the boot menu. Unlike the Windows Mobile/Android dualboot procedure, which was common before the release of MAGLDR, this dualboot system doesn’t require any boot up in one OS before you can go to the other. You can just choose directly from startup.

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.
It is not possible to have both WP7 and Android in NAND, because of the partitioning WP7 does to the memory. So, you will inevitably have to use the SD variant of the Android builds – which will probably not be a big problem for most of you. So get yourself two SD-cards, SD partition software and a good cup of coffee, and continue on to the thread!_________
