HP Pavilion 500-164 Desktop PC MS-7778 Ver. 1 Bios Wont Keep Boot Settings

[jonnynights]

I can not get the bios to remember the legacy boot settings. The computer will not boot from USB, CD, or HD.

I have intermediate skills with computer repair. I have been out of it for about five years.

I have replaced the CMOS Battery, moved and removed the jumper to clear CMOS in different ways with powering down and powering up the computer. 

I tried switching cables and the slots on the board itself.

A lot of people in these forums online have made suggestions in the past and I have tried many of them.

I do believe the motherboard functions as should, I mean it does power on and gives me the "No Operating System on Device" Screen.

Oddly enough, early on I was able to put in a Windows 10 boot disc in the CD tray and it did boot into the Windows repair screen, but for some reason, none of the options worked. I have yet to get an operation CD to boot.

Nothing boots from USB drives.

My Hard Drive is good.

I was told to put a program called Rufus on a CD and put the BIOS update.

After searching the endless pit of the PC repair online world I have yet been able to find this update. I have looked directly on HP, and at other places.

Please help.

Let me try to address some of your issues...

You did the right things regarding the CMOS reset and battery replacement for the boot settings issue.  I do not know why those did not work as they SHOULD have worked.

You're most likely NOT going to be able to update the BIOS.  Why? Because the latest OS version that HP supports with BIOS updates is Windows 8.1, and the HP BIOS files are OS-version specific.  This means, those will not work with Windows 10.

As to RUFUS, that is a utility that is used to create boot media.  The only value in putting it on a CD would be to use that to copy the app to a PC that can read the CD.  The app has to be installed to work; it can not be run from portable media.

All of that said, there are folks in these forums that have access to BIOS updates I do not. So, if one of them comes along, they might be able to point you to a BIOS update you can apply.
