Hello, I’m sorry for posting in this thread, could some please help me. I have a strange problem, which is that when I turn on my computer it tells me to put the original windows disk, and then select “r” for repair at the first screen. It asks me what to repair. (c:windows) and then my administrator password. The problem is I don’t know it. I have had the computer for about a year and have windows xp pro with sp2. This started happening after a power outage and my battery backup failed on me. Please help me I’m having a bad day.
