Rather than wanting to install a 2nd copy of XP on the same drive/partition, I need to remove a 2nd copy that was 'accidentally' installed on a 2nd drive/partition. The original was XP HE w/SP2 update installed. The 2nd was supposed to be a repair of the C: drive following a crash [BSOD] and thence became inaccessible due to a corrupt system32\config\system file. It was installed on another partition, drive F:, which was supposed to be for data storage, and is the OEM revision, with no programs, etc. added. I did get my original C: XP to work now and want to get rid of the 2nd on F:. In Disk Manager it shows C: as healthy and 'system' & F: as healthy and 'boot', both are basic disks, no extensions. What procedures do I follow to uninstall the F: windows installation, but hopefully keep my data files; although as they are few they could be moved temporarily until XP is uninstalled; then re-added. F: is labeled 'My Files' with Windows as a folder, added between the other data file folders. [step-by-step, simple please]? How do I get the 'system' and 'boot' into the C: Drive partition so that the boot, etc. files are all available upon windows booting to C:? Thanks, Gateway 2000E XP HE [OEM installation CD] D.D.
