SOLVED - THANX !!! Boot CD for formatting

[Flashlab]

Do you happen to have a SATA harddisk? XP doesn't see those by default as it has no drivers for it.

If that's the case then search in your BIOS for IDE compatability mode for your SATA settings and XP will see the drive.

It's SATA that's the problem; if there's no IDE compatability mode in the BIOS then you need to load the drivers from a floppy (press F6 when the XP install tells you so for external drivers).

Or when you have a laptop or other preinstalled computer just use the recovery CD/DVD.

You can also make a XP cd with the drivers included. I believe it's called slipstreaming.

Do know that when you change it back Windows won't boot anymore! There are ways to install the SATA driver afterwards but that requires some tweaking.

Did you change SATA back to AHCI?
