There is no system restore on Windows 2000
Boot from the OS disk and use repair mode or use last known good configuration
Begin the repair process
You must boot from your 2000 CD. Please make sure it is the same version of Windows that is currently installed on your computer Place the CD in your CDROM and start your computer. Newer versions will work as well
Before the Windows logo appears, you will be asked to press any key to boot from CD, so do just that.
A blue screen will appear and will begin loading 2000 setup from the CD.
RAID/SCSI/Unsupported UDMA users:
You will be prompted to “press F6 to install any third party SCSI or RAID drivers”. Most users will not have to press F6, but if you are running RAID, SCSI or unsupported ATA controllers, then you need your controller drivers on a floppy disk. If you are unsure whether you have RAID/SCSI, then simply let the CD load without pressing F6.
Once completed, you will be confronted with “Windows Setup”. You will be asked to setup up Windows, or repair Windows with the recovery console. Choose the FIRST option, NOT recovery console.
Next, Windows Setup will find existing Windows 2000 installations. You will be asked to repair an existing installation or install a fresh copy of Windows 2000.
If no installations are found, then you will not be given the option to repair. This may happen if the data or partition on your drive is too corrupted.
That should be it. Windows 2000 will appear to be installing itself for the first time, but it will retain all of your data and settings. Just follow the prompts, have your CD-KEY handy and hope for the best!
