I want to repair my Windows XP, but my laptop's DVD ROM doesn't work, and all the time I've had to boot from a USB drive to install an OS. So now I want to repair Windows XP due to some problems.
I use Magic Disk virtual DVD ROM, but when I repaired while my DVD ROM was still working, the driver of Magic Disk was uninstalled by setup. So now I don't know exactly how to fix this problem by USB because every time it prompts for one of two steps
1: Boot from USB for 1st setup, i.e., Console part.
2: Boot from USB for 2nd setup, i.e., GUI part.
So I'm nervous that I will do something wrong that cost me a reinstall. I'd prefer the way of virtual repair, if it is possible, otherwise I'd appreciate knowing about how to repair through USB.
