Windows 7 dont boot in CD

Thanks for answer ...But The pc from i am writing from i have installed the windows 7 that i am trying to install on the other computer and it not even boot in the cd !!!

First check for all the Win XP drivers for your hardware.
If your Win XP CD, does not support your Sata Controller, you will need to load drivers to uses at F6.
Load Sata Controller drivers with a floppy disk is the best way.
SATA Drivers - Load in Windows XP Setup on Dual Boot
OR
SATA Drivers - Slipstream into Windows XP CD

You download WinXP drivers for AsRock N68PV-GS from here:
ASRock > Products > Motherboard > N68PV-GS > Download
or
You may find them on the driver CD.
