Errors

Missing Operating System
This error occurs when the boot record signature of the master boot record does not match a certain value at a certain location. In this case, the boot sector is invalid and the computer cannot boot. This error can also occur if there is no active partition defined in the partition table.

Non-System Disk or Disk Error
This error is generated by the computer's BIOS when the boot sector or master boot record of the boot drive is damaged or missing. This error can also occur if the boot device has been improperly configured in the BIOS. In this case, data in the partition may be valid and undamaged, but there is no bootable partition. NOTE: This message also occurs when a non-bootable disk is left in drive A during startup. If you receive this error, make sure that there is no disk in drive A and restart your computer.

Boot Error Press F1 to Retry
This error is generated by the computer's BIOS when the hard disk is missing a master boot record or boot sector, or when there is a problem accessing the boot drive.


NO ROM BASIC
If there is no active partition defined, the master boot record returns an error to the BIOS. In some cases, the master boot code attempts to go to ROM Basic when no bootable disk is found. Since some computers do not have ROM Basic, they display a NO ROM BASIC or other error message. The message displayed is dependent upon the computer's BIOS.

Invalid Media Type
This error message is displayed when the boot sector of a defined partition is damaged. The error message is normally received using a new partition that has not been formatted. However, if the boot sector is damaged, the partition may appear unformatted to the operating system, and this error message is generated.

Hard Disk Controller Failure
This error message indicates either the hard disk controller has failed, the hard disk controller is not set up properly in the BIOS, or the controller cannot communicate with the attached drive(s). In this case, do not perform the troubleshooting steps below. Instead, consult the documentation included with your computer or contact the computer's manufacturer for more information.
