This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
The BIOS can be configured to specify the order in which the computer will access available bootable hardware devices. The most common bootable devices are: Internal Hard Drive, External USB drive, Optical CD/DVD ROM Drive, and Network Adapter. During the process of checking each device for the required bootable files, if a device fails, the computer verifies that another device is available. If it checks all the listed devices but does not find the bootable files, an error message, like the following, is displayed.
Boot Device Not Found
Hard Disk - (#####)
To resolve these boot device errors, perform the following steps in the order listed. If the computer still does not start, contact HP for assistance with this error.
NOTE:If the notebook boots successfully after receiving this message running a hard drive test is strongly recommended.
The HP Hard Disk Test may be able to fix errors while testing the hard disk drive. To correct this issue, do the following:
Press and hold the power switch for 5 - 15 seconds to turn off the notebook.
Press the power switch to turn on the computer, and immediately press the Esc
On the HP Startup Menu, press the F2
System Diagnostics key.
Select the Hard Disk Test
Once the Hard Disk Test is completed, attempt to start the notebook normally.
If the Hard Disk Test cannot fix the error, it will display a failure code
and a Warranty ID number
. Contact HP Customer Support. The Warranty ID number is required to determine if the HP Customer Support agent can authorize repairs or part replacements under warranty.
If the hard disk test passes, the hard drive itself is functional. However, the operating system files may have become corrupted or have been deleted. Use System Recovery
to reinstall your operating system and all HP-installed software, returning your computer to its factory image. For more information, please refer to
