I completed my first built computer the other day but am having issues with windows. When I install it it gets to the part where it says it is copying files and comes up with the message saying some files are missing. I managed to borrow a copy from my dads work incase I had a damaged cd but it does the same bringing up the same files as missing. I tried skipping but this brings up a fatal error later, I cant see that I managed to get two faulty cds so could it be a hardware issue?
