    Windows 10 Pro x86 and x64 dual boot

    I have three partitions assigned as OS on one of my drives. I installed Win 8.1 32 bit as a dual boot with XP. Then on the 3rd partition I installed Win 8.1 x64 to try with hardware, but some hardware isnt supported. I then started the Win 10 upgrade from the running Win 8.1 x64 and that went ok. Have Win 8.1, Win Tech Preview and other OS (XP) all bootable. I removed the rollback entry using the Boot Tab in MSconfig. Anyway thats how I did it, although I did notice in Win 8.1 after Win 10 was installed the task manager had been reset as if it had just been installed. Not sure if Win 10 did that.
