Ok the title says it all, i have vista home basic, and i'm fed up of it, i also have windows xp professional of which i want 2 put on, i press any keey to boot from cd, before i get the options on the windows load screen i get a blue screen with some 0x0000000007 or 8 i cant remember but is there anyway to get poast this? would i need to format the harddrive in a different way first? i think i should mention i have a Dell e520, any ideas?
