Had a dual boot system on two physical disks. Hard drive w/Windows XP as the OS crashed and had to be removed. Remaining drive was 20GB with Win2000 Pro as the OS. Made a partition on the drive and installed XP. Everything works fine but the XP volume is a little slower than I would prefer. That aside, I prefer Windows 2000 (C:\) over XP (D:\) anyway. Now I want the uninstall XP and the partition. From what I can see all sys and config files are located on C:\. 1) Can I just format D:\ and delete the partition? 2) What files do I have to make sure are available on C:\ so that the system will boot after removal of D:\? Comments, ideas and suggestions are needed. That you very much.
