my comp has had a problem when i installed nortan go back, when i turn my comp it does the intel logo, and the white text, then it goes to a nortan goback screen asking me to press space bar to repair boot errors, i press it but it reboots and does the same thing. i tryed to boot in safe mood but it wont work. so iv been trying to install 2000 to see if that will sort it, but it doesent boot up, i tryed to use xp boot disk but it say my cd drive isnt conected when they have loaded, any ideas with whats up?
