I have a laptop that ran ok on xp home and i managed to get a copy of the new windows 7 evaluation cd. i tried to install it and it came up with graphics card error my graphics card was not powerfull enough so i switched off and thought i will stick with xp, then after that when i try booting it comes up asking if i want to load xp or windows 7 but when i choose windows 7 it just blue screens and i have to restart it. if i choose xp it loads up ok as usual. I tried to get rid of this duel boot by trying to install a fresh windows xp and when i tried it said i have an newer version on my laptop but it tried to install xp, then half way thru it blue screened and now it wont boot at all it keeps looping, when i boot up i have 3 options earlier windows version which when chosen it just keeps looping and going back to the choice screen ,windows setup which when chosen comes up with cant boot file missing or corrupted and then finally windows xp setup which when chosen comes up with a blue screen. if i try loading another windows again it comes up saying it cant find my hard drive but the bios finds it perfectly.cant seem to get round it tried all the F keys but the only one that works is the one that lets me get into the bios. can anyone help ?
