I disconnected the new Win 7 drive and reatached the old XP drive, but it BSODed as I had changed the BIOS SATA config from IDE to AHCI for my new Win 7 HDD.
The Win XP HDD will work but I have to remember to change the SATA config back to IDE first in the BIOS.
I need to know if it's safe to boot my Win 7 HDD together with the backup drive in AHCI SATA, mode as the backup drive was formated from the Win XP setup which was under IDE?
I don't want to risk BSODing my backup drive and corrupting it.
Can I boot the Win 7 drive along with the backup drive in AHCI SATA mode?
