Okay, so I have a recent laptop I bought. It came with Windows Vista. Well I decided after trying it for a while, that I wanted to switch back to XP for now. So I bought an XP disc off NewEgg. So I open it up, and put it in the drive, and then restart my computer. Thats where the problem occurs. It goes through the whole routine of inspecting the computers hardware. Then gives me the option of installing XP or trying to repair an installation. So I of course chose to install it. Then it says, it can't install cause there is no hard drive installed. Why is it reading that error? And is there any way to fix it? I mean I obviously have a hard drive installed and working. Cause vista is running on that hard drive. So I don't get whats going on. Any help?
