Problem

Symptoms: The customer's computer no longer boots from the hard drive. Solutions: Physical damage to the hard disk may exist. Also, the hidden DOS system files could be missing from the root directory (e.g., C:\), or the DOS system files could have become damaged. Boot from a DOS diskette. Try logging onto the hard drive by typing C: and pressing Enter. If you receive the error message "Invalid Drive Specification," the hard drive or its controller is probably damaged. Refer the customer to the hardware supplier for assistance. If you are able to log onto the hard drive, a missing or damaged file is probably causing the problem. Log back onto the floppy by typing A: and pressing Enter. At the A:\ prompt, type SYS C: and press Enter. This will copy the hidden DOS system files onto the hard drive. Then type COPY COMMAND.COM C:\ and press Enter. This will copy the COMMAND.COM file to the hard drive. (Usually, if this file is missing, you will receive the error message "Missing Command Interpreter.")
