There are several causes for this error message. The boot sequence may not be properly set in the system BIOS. Another cause is the presence of non-bootable media in the floppy or CD-ROM drives. The drive may not be properly configured or detected in the system BIOS. Incorrect Jumper Settings or a defective IDE cable may also be responsible.
- Make sure that your boot sequence is correctly set. Generally, you should set the boot sequence to boot to the floppy drive first, then the hard drive, and the CD-ROM drive last.
- Check your floppy drive and CD-ROM drive for media and remove any that you find.
- Verify that your drive is properly detected in the system BIOS.
- Verify that your Jumper Settings are correct.
- Power off the system, replace the IDE data cable and try to boot again.
