So my sis has an NEC Versa s970 laptop which came with vista business edition. She wanted to install XP pro on in instead, but heres the problem. When I do it via the standard boot menu (press key to boot from CD bla bla bla) after it sets everything, it shows up with a problem, it says "There is no hard disk found, setup cannot continue". And if you do it via windows, the option to "intstall XP" is greyed out.
How do I go about doing this? Help!
