Shut down your computer. Press the power switch to turn the system back on and directly after continuously press the delete (F1 or F10 depending on your system) key to get into the BIOS. Select “Advanced BIOS Features” (use arrow keys to highlight, press Enter). Change the boot order to boot to CDROM first and then to SCSI or SATA second.
Then press F10 to save and exit (put the 2k3 CD in before you exit).
After the reboot, press any key to boot to CDROM, and the 2k3 setup should start.
When the blue 2k3 setup screen first appears you will see a prompt at the bottom that says “Press F6 to install any RAID or SCSI drivers”. Press F6 at this time.
It will not respond immediately so be patient. After it finishes loading a few more files, a prompt will come up asking you to press “S” to install any RAID or SCSI drivers. Press “S” and have your Promise drivers for 2k3 or XP on a 3.5 floppy in the floppy drive.
The 2k3 setup will read the floppy and may ask you which drivers you want to install. Pick the drivers for 2k3 or XP and eventually it will go back to the first prompt. Then press “Enter” to continue loading Windows.
When prompted, press enter to install 2k3. It will find your previous install and give you several options. Pick the "Repair" option. The 2k3 setup will delete your previous Windows folder and replace it. After it’s all done, you can reboot, get back in the BIOS and set the boot order back the way it was. I usually set the first boot device to HDD-0 and disable the rest.
Any tweaks you may have done to 2k3 will be un-done after you use the repair option but all of your data will be intact. You may also have to re-install some programs and you will have to update your most, if not all of your drivers
Good luck!
