You have a Windows install disc, so do this......................
No format re-install of Windows XP
What you’ll need-
A Windows installation CD with the serial key.
First enter ‘Setup’ – When booting up (before Windows loads) keep tapping either Del, Esc, F2 or F12. Depending on your system, one of these will get you into ‘Setup’. Once there, change the ‘boot order/sequence’ to boot from the CD/DVD drive first.
Insert the Windows CD, save and exit. If you don’t get a screen saying ‘Press any key to boot from CD’ re-start. If you do, then press a key.
When it boots up from the CD you’ll see a screen with ‘Setup is inspecting your computer’s hardware….’ then the ‘Windows Setup’ screen.
After a couple of minutes, you’ll see a screen with ‘Windows Setup-Setup is starting Windows’
On the next screen ‘To setup Windows XP now, press ENTER’ press enter.
Setup will now look for ‘a previous version of Windows’ If your copy of Windows isn’t highlighted, do so now. Once it’s selected press ‘R’ for ‘Repair’.
What happens now, is that Setup will find and delete corrupt or damaged system files and folders, then replace them with new ones from the CD. When the new files have been installed, Setup will rebuild any damaged parts of the registry but leave the rest as is. This means that you don’t lose any of your installed drivers/programs.
Once Setup has finished this part of the process, it will automatically re-boot, so you have to remove the CD (replace the CD once the boot has finished).
The first re-boot will take some time so be patient. When Setup starts again don’t panic! It will look as though you’re doing a full re-install, you’re not, it’s part of the repair.
The next couple of screens will ask for language settings and the serial key, enter them. After giving this information the next two or three screens can be ignored, they will move along a lot faster than the progress bar indicates as none of the settings have been changed.
When the repair is finished you’ll see the ‘completing installation’ screen, then the system will re-boot, again, this will take longer than usual (remove the CD).
You’ll next see a ‘Welcome to Windows’ screen then be asked if you want to register and maybe to re-activate depending on how bad the damage was. Complete the screens as necessary.
The last screen is the ‘Thank you’ one, the system may re-boot once more normally.
That’s it! All done.
