Hello,
I have a big problem, i installed Windows 7 on a friends computer without any driver(because the drivers work only on Win 2000 and XP). He doest have internet connexion. I want to install Win XP, then install his drivers, but when i restart the CD won't boot,(I had done that to select the CD 1st option and HDD 2nd)
What can i do now? I can't install XP now, and on Win 7 i can't install any driver. HEELP !

If the Windows DVD booted but the XP CD won't then there must be something wrong with the CD. It is a genuine Microsoft CD?

Disable all boot devices, except for the CD/DVD drive in the BIOS. Use a few drops of water and a soft cloth to clean the XP disc. Then try booting off the disc.

Mostly it's unavailable to install Windows XP after Windows 7 because it's a huge propability that errors may occur, such as " Disk boot fail" Press CTRL+ALT+DEL to restart, your Boot Manager will not be able to boot Windows XP, etc. I spend all night in order to figure that out and the results was failure all the time. But I found an even easier way to do it but it will cost you a HDD format.
Follow these few steps and I hope they will help you.

1) Format your C: HDD
2) Split the C: HDD into 2 partitions.
3) On the first partition install Windows XP.
4) On the second partition install Windows 7, since the Boot Manager is much newer than that of Windows XP.
5) When you manage to do these, whenever you will boot your PC, the Boot Manager will show you 2 options:

Older version of windows (which is windows xp)
Windows 7

so now you can choose which windows you will operate.
It worked for me so I think it will also work for you.

That's because Microsoft states when dual booting, the oldest OS must be installed before the newer OS. It has always been this way with microsoft OS's. The XP loader doesn't know how to load 7 because it's newer (thus the disk boot fail error). The win 7 loader does however know how to load XP.
