|So, if you are able to use Nero then you have Windows already installed on another drive? What type and size is that drive? What SP is installed? |
Watch the POST screens at start up to verify that ALL your drives are properly identified by both model and FULL drive capacity. If they are not showing then you either need to set the BIOS to use AHCI settings for the SATA ports or install the SATA controller drivers in WinXP, if that is possible.
Why are you doing that anyway? Are the drives used or new? All SATA II or SATA I? Is the CD drive also SATA?
If so, you may need to change the setting in the BIOS and also may need to use only certain SATA ports.
