i currently have vista 32-bit. I want to get windows 7 ultimate and i like the windows xp mode option. My only concern is if i get 7 in 64 bit will the windows xp mode be 64 bit? I can't have xp 64 bit because i will not be able to run my school programs such as XILINX
I am currently running Windows 7 RC 64 Bit, and Windows XP Home 32 Bit on the same machine in dual boot configuration, there is no incompatibility problems, no "confusion" with the 2 different operating system modes. I have partitoned a 160GB SATA drive in half, and run W7 64 Bit, and XPHome 32 Bit, on the same HDD.
If I can get away with this, then you should have no problem running them both. I hope this helps?
