hey guys i was running vista ulktimate on my pc however my wifi dongle isn't vista capable so i decided to go back to xp. i formatted the HD and went through the steps on xp to the part where all the files had been copied and the computer needed to restart. upon restart a message appeared press any key to boot from cd so i left it (as i have done all the times i have installed xp) and then the message just stayed on with a blinking cursor next to it. if i do press any key it goes back to copying the files again (sometimes) or just displays a blank screen. the same now happens for vista the setup goes fine but after restart i am confronted with this message. now no OS will load on. what do i need to do?? i know it isnt the DVD's as i have done this procedure before on other computers and the one i am trying on now. willl i need to get a nerw HDD or something . Thanks
