My friends PC has win XP home, with no recovery disk, other than XP disk. She can't boot her PC, or get it into safe mode either. She gets a message Windows would not start because the following file is missing or corrupt:\system 32\config.sys.and telling her to insert the Win disk and repair the file. I have set it to boot from CD first and HD second,as a message appears stating that the PC has no HARD DRIVE, and cant read the CD. Yet when I go into the raid configuaration (it has one SATS HD) which I can see. I don't know whether its the HD or the MB or...power supply?.
