No Hard disk detected / boootable device

When the computer/laptop cannot see a boot file/disk on either the hard disk or floppy drive it gives an error message - "No bootable device. Insert boot disk and press any key"

First thing, check to see if the is a floppy disk inthe floppy drive, if so removes this disk.

If there was no disk in the floppy drive then it maybe a hard disk problem.
Check the BIOS to see if the hard disk is detected, if not open the case and re-seat the data cable on the hard drive and also where it connects to the motherboard disk controller.
If it still gives this error message and the BIOS does not detect this hard drive, then the hard drive is probably faulty.

A further check on the hard drive, remove the hard drive and connect it to an USB hard drive adapter and connect it to a working computer's USB port, if this computer does not detect it as an external storage device then the hard drive is faulty.

To get the computer operating again, install a new hard drive in your computer and then install Windows on this hard drive plus the computer's device drivers and your programs.

I have a HP 8595c computer. I put a DVD in and it froze. I restarted the computer and now it won't boot up proberly. I get this message. "Non-System disk or disk error Replace and strike any key when ready." When I do that the error message just keeps coming up.


Non-System Disk or Disk Error results when the Basic Input/Output System (BIOS) cannot find the boot sector or the master boot record is missing or damaged; i.e. the device does not have bootable media. The BIOS searches drives in the order usually specified in the CMOS Setup. This order is often, but not always, A: (floppy drive), C: (first partition on the hard disk)… The error will occur during startup if the CMOS is set so the BIOS seeks the floppy drive first and a non-bootable (or blank) floppy is in (was left in) the floppy drive. Other causes include:

No bootable partition on a hard disk drive
  • A defective hard disk drive
  • The CMOS drive settings (parameters) are not correct for the boot device
  • Defective floppy
  • Defective floppy drive
  • A virus
