I realize this is about windows, but is a primarily desktop related plea for help.
I've just build a new computer (first time I've done it), had it checked over by my brother-in-law who knows more about computers than I do. He gave it the all clear, so I'm fairly sure it's not a hardware issue...
I have only 1 copy of Windows 7 Professional, and I can't transfer it to the new one (as its running on my old PC). So I installed it anyway only as a trial to see if everything was running smoothly. It loaded fine and everything was working smoothly. (note: I did not authenticate or update Windows 7) I then proceeded to install the drivers for my motherboard. Whilst installing, the PC restarted and Windows crashed as it was loading. I tried again to see if it was a once off, but no, it happened every time. I tried safe mode, still wouldn't load. I gather from this, the Windows files must be corrupted in some way.
I tried to boot from CD drive but it kept reverting to HDD, not sure why as I changed the BIOS boot sequence and chose CDROM from the boot menu.
I've now decided to just format the HDD and start over with a new copy of windows, but I can't do that without booting from the CD drive.
Please help!
