|In addition to the above, if you have a SATA hard drive and intend to install WinXP, be aware that WinXP doesn't support SATA hard drives natively. You need to supply SATA drivers. |
So, if you have a SATA hard drive you will need to slipstream the SATA drivers into your WinXP files and then make a new CDR. Use nliteos to perform that operation. Get nliteos at the link below. Get the SATA drivers from the laptop manufacturer.
Also be aware that if you are downgrading from Vista or Windows 7 you may not find drivers for your hardware. Check BEFORE proceeding.
