# Windows system drive letter changed after repair install

drive-lettermulti-bootrepair-installwindows xp

yesterday I did a repair install, because Windows froze on welcome screen after resizing its partition on a dual boot system. corresponding question

Everything worked fine so far, but now I am facing another challenge: The Windows drive letter changed from G: to C:, so that most programs, including drivers, firewall and virus scanner do not work anymore. I tried to reinstall the virus scanner, but the uninstaller said, that drive G: is not available.

What to do now, to get all programs running again? Is it possible, to rename C: to G: or will that mess up my system?

There is 19 steps procedure in that article, I'd rather not copy them all here. One note, though: regedit32.exe is mentioned there, regedit32 is not available in XP. Just use regular regedit, right-click and chose Permissions as the article says.
