I have a gateway machine that came with VISTA loaded and I decided to go back to XP Pro. The laptop has only one WD Sata drive; using LINUX I deleted the NTFS partitions that had VISTA on it so the drive should be clean. Now, when I try to install XP PRO the installer says that it cannot detect any hard drive on the computer. I have gone out to the western digital site and tried many different drivers by slipstreaming them into the XP installer with no luck. I'm sure I'm not the only person who has had this problem, Please, I need help.
