A few days ago i ran a disk defragmentor and than shut off my computer when it was completed. The next day i turned it on and it said that it could not load windows becuase Windows\system32\config\system was either corrupt or damaged, and to repair it i need my OS disk. I have home edition, but the only disk that i could get my hands on is the proffessional edition. So i put it in and hit "r" to repair the OS. Now it brings me to a prompt and asks me to select a disk drive. I selected my disk drive, and it just says
When i typed help it listed many different commands that i could use, but im not sure which one to use.
