DOS Boot Sequence Error Messages
Error Message	Condition	Correction
Missing operating system	The MBR can't find a bootable partition or there is a boot-sector virus.	Format the drive with FORMAT/S or run a virus scanner.
Non-system disk or disk error, replace and press any key	Usually means that there is a floppy disk in the disk drive.	Eject the floppy disk and press any key.
Incorrect DOS version	The COMMAND.COM in the root directory and an internal command, issued in either of the CONFIG.SYS or AUTOEXEC.BAT files or at the command prompt, are not of the same DOS version.	You need to either find the correct COMMAND.COM or use the SETVER command to trick DOS into believing that it's running the correct version. This problem is common with CD-ROM drivers.
Error in CONFIG.SYS line XX	Something is incorrect in CONFIG.SYS	Use EDIT to examine and correct the problem. If a line number is not given, use F8 to find where the problem occurs.
Bad or missing DRIVER.DRV	If CONFIG.SYS can't load a device driver, it issues this message.	Locate the driver and correct the entry in CONFIG.SYS.
Bad or missing COMMAND.COM	The COMMAND.COM is damaged or not in the root directory.	Copy a new COMMAND.COM to the root directory.
