Basically for some reason on reinstall Windows has named one of my other drives to C: and my main drive with Windows on as E:, now i can't change the drive letters because the C: drive is the system drive
and the E: drive the boot drive, what can i do without formatting the C: labeled drive to change my E: (Windows drive) back to drive letter C:. Iv'e had a problem like this before with XP setup but forgot how to sort it.
