Hello again lisior.

Sorry to see you had an issue though I'm at a loss at what it could be; did you have Linux installed at any other time?

First of all, thank you for this tutorial BFK. I have been reading through quite a bit of threads where you and Brink have been helping others with similar issues. I kind of just mixed and matched different advise that the two of you have given, before I found this thread. Turns out I did almost exactly what is described here, except for the "wipe" (I just deleted my first partition, which was Vista, with Partition Wizard) Turns out, I ended up with the same problem as lisior. I can boot to Windows 7, but after I log on it says "preparing your desktop", and after waiting longer than usual it brings me to a blue screen that says "Windows 7; Build 7600; This copy of Windows is not genuine" in the lower right corner. I followed prodigy's "Possible Solution" here:
Booting Problem related to Windows not genuine error
Which fixed the problem, but now my only partition, which is the Windows 7, is labeled as F: I tried to use Disk Management to change drive letter and paths, but it throws me an error about parameters. I know that it doesn't really effect anything to be labeled as F:, but I was just wandering if you had any insight as to something that I could try to get it to work correctly, labeled as C:?

Hello Chris H.

To get a letter 'not' C: you must have installed Windows 7 from within Vista and didn't boot from the Windows 7 installation disk; unfortunately there is no successful way to change the drive letter for a Windows "System" partition and if you did manage it there would be all sorts of issues following; when you installed programs/apps they were created to use the "Letter F:" and that can't be changed short of a Windows reinstall.
