My computer has had a rough day My HP with preinstalled XP (meaning I don't have the disk) decided to not work this morning, restarting itself right before it should have entered the Windows screen, making an endless restart loop. Consulting with some knowledgable friends, I decided that since I really didn't have anything I needed on my harddrive, I would format the C partition and reinstall Windows with my dad's Windows XP disc. The format went well, then while installing Windows I got all these errors about File Missing. I realized that my dad's XP disc was in fact a ME/98 Upgrade Disc.
