Problem installing XP

[PureAppleJuice]

Hi there, just sorting out a newish system of my sister's (6 months old PC), she was sick of vista so i'm replacing it with XP for her. Problem is, when I boot from CD and commence setup, it just states the HDD as an 'unknown disk' and pressing anything presents me with a BSOD.

Any ideas what it might be? Says it's a file error, so perhaps something wrong with the disc?

Well solved it, formatted the HDD completely in a seperate PC twice and still no luck. Then I realised that it was running in RAID mode and not IDE so the XP installer wasn't picking it up as I assumed I didn't need drivers
Bit of a schoolboy error there!
