Okay I just purchased a new laptop (Inspiron 1720), but unfortunately the only options Dell offered as far as Operating Systems go, was some variation of Windows Vista. Let me be the first to say that Vista is a piece of crap. Now I am trying to revert back to XP Pro (SP2). My problem is this: I had to set the CD drive to boot first in the boot order, but when I boot from the CD my computer apparently doesn't detect the presence of my hard drive. After I press ENTER to install a fresh copy of XP, I get a message saying that no hard drive was detected and that I must quit setup. There is nothing physically wrong with my hard drive, as I am able to boot from it (once I change the boot order back) with no problem. What am I missing here???
