So, I had this HP Pavilion G6 from 2011. I recently found it and tried to use it, but the hard disk was broken. I changed it, and installed Windows 10 from USB/ISO downloaded from Microsoft's site.

Almost everything is working OK, but there is a problem: (when the PC is off), when I press the F5 key, the PC starts up, and it shows a BIOS Error 501 or something, I found out that's because I don't have the HP_Tools Partition on my drive (as I installed the "vanilla" Windows and not the OEM, I suppose).

My question is: can I rebuild/create a working/populated HP_Tools partition? Or download an OEM ISO?

HP_Tools Partition contains Hardware diagnostics, which is important when diagnosing a problem, but is not essential for booting. If you have tried to run the diagnostics, then it's only natural that it failed.

According to HP PCs - 500, 501, or 502 Error Displays on a Black Screen the BIOS problem is either with a corrupt BIOS or with a missing EFI partition. The later is unlikely in view of the age of the computer.

You may download a BIOS update from the HP website at the HP Customer Support - Software and Driver Downloads page.

When installing Windows, assure you are using a non-EFI boot and that the BIOS is set to Legacy boot (if it has such an option).

  • Yes, my PC is non-EFI, and Windows runs in BIOS mode; that's not my question. I am asking how/if I can re-create the HP_Tools partition on the new disk. The HP site didn't help, as it didn't show correctly, I'll try again later with a different browser. But anyway, I don't think this is an issue I can fix by updating the BIOS, as I think I have the latest update, I'll check, that later also... Thanks anyway

  • You need to find an HP boot installation media for Windows, for it to create this partition. If you don't need to update the BIOS, it's better to avoid it on such an old computer.

  • While your answer didn't solve my problem (yet) what you say isn't wrong
