That's a standard message in case the BIOS can't find a disk (hard disk, DVD, diskettte) or USB device to boot from. So the hard drive is suspected.

- First reset the BIOS to what it was or to something like "safe defaults" and try again.
- If that doesn't help, see if it boots from your Windows install disc or stick (or the recovery drive you made) and run a chkdsk.
- Or boot to the built in diagnostics partition if your PC has it (most Dell machines, for example, come with that) and run the diagnostics.
