27" HP-Pavilion All-In-One PC
Well, I screwed up.
Trying to install Linux on it and could not get it to boot after the install.
Some kind of issue with UEFI and Legacy for booting.
Since Microsoft uses Secure Boot, I went into the BIOS and started disabling Security on areas, USB being one of them.
Now the keyboard doesn't respond, so I can't get back into the BIOS to fix.
I've removed the CMOS battery twice, pressing and holding power button for more than 30 seconds to drain any charge.
When I rebooted, I got a red box saying to "Press RETURN" to reset the BIOS to factory default.
Well, can't do that because keyboard doesn't respond.
Found one thread about doing a hard reset (remove power, hold power button for 15 seconds, restore power) and use a wired keyboard.
That didn't work either.
I'm stumped.
Any ideas ???
Thanks

You will need a wired USB keyboard. Plug the keyboard into a USB2 port. If you are not sure which one is USB2 then turn on the AIO and plug the keyboard into any USB port and watch the LED to see if any light up or flash then you turn on the AIO.
It might be difficult to get into the bios on a fast system. Try the hard reset
Turn off the computer - hold power button down for 30 full seconds then release. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings. Press F10 to Save and Exit
When you create the Ubuntu boot USB be sure to select the UEFI and GPT option in Rufus or whatever too you use to form the USB boot. Do not use MBR. Ubuntu should boot and run fine without installing on the drive. if you want to run it off the main drive I recommend you replace the hard drive. If you install on the hard drive you will erase the HP recovery and backup bios.

Thanks Beemer.
I guess I wasn't holding the power button long enough when I tried the Hard Reset.
That resolved it.
Strange though, when I got in and did a Reset to Factory Defaults, it did not reset the Security settings I had made.
I set them back and all is good now.
Thanks again for the help.
Have a good one...

If you want to try out Ubuntu, get a cheap used mining motherboard with memory and CPU. Add a cheap power supply and after setting it up, use your AIO to remote desktop into the Linux system. Or a socket 1366 system like this one and use risers if a graphics card cannot fit in any socket..

I use Debian (very similar to Ubuntu).
Have it on 4 Servers (2 AMD Rizen 5 & 7, and 2 Raspberry Pi 4)
Hardware Rail 1 in the AMD Servers.
Also built a couple Raspberry Pi 4 computers for friends.
When I upgraded one server to an AMD Rizen 7, I build a PC with the MB & CPU from the server for my wife, to replace the aging/slow WIn-10 AIO.
The AIO should have better performance running Linux.
That will go to a friend as well.
