Booted from my win2k CD and went to Setup. Press F8 and accepted EULA. Then chose to repair the selected Windows 2000 installation. Setup copied files to the win2k folder, then it initialized the win2k configuration. PC was then rebooted. Got win 2000 gui at starting up of the OS. After gui screen nothing appeared and win2k failed to start. The hard drive passed the following tests with SeagateTools for Windows: Short Drive self Test, Long Drive Self Test, Perform a sequential short read on the drive, Perform a sequential long read on the drive. How can I fix the OS?
