Hi, I have Vista 64 on C: and Windows 7 RTM on F: running simultaneously. I've got Win7 to the point where I can abandon Vista entirely. I was wondering if I could image the Win7 F: drive -- I use Acronis TrueImage -- and replace it onto C: eliminating the Vista instance for the Win7, then reclaiming the F: drive space for other use. I guess my concern is if it will boot and/or run properly if the drive letter changes. Will I be required to reinstall just to get it to C:? Thanks for any advice!
