I disabled UEFI in BIOS. Now, machine won't start. Can't even get back to BIOS. None of the recovery steps I've found fix the problem. I really just need to reset the BIOS to factory defaults. <Windows>+<B> doesn't do it. Resetting the CMOS jumpers doesn't do it.

Welcome to the forum.
I am not a HP employee.
What did you do in the BIOS to cause you to think you disabled UEFI?
Your PC sports a 7.16 Rev. A BIOS.
This BIOS version does not support a UEFI BIOS. UEFI BIOS versions start at 8.xx.
You have a different problem, possibly hardware failure, if the PC will not POST (Power On Self Test).
I don't think this Legacy PC supports a BIOS recovery.

That would be the one. I was running the machine just fine but struggled to default to a boot from CDROM. All I remember (& at 74, that alone can be a problem) is the last thing I did was "disable" two settings about "UEFI programs". As soon as it tried to do the re-boot, it black screen. 1st time I've ever done that. Always been able to go back to BIOS setup before when machine wouldn't boot.

I've had this computer since 2011. Actually been a more than satisfactory for supporting my home network. Currently has 8GB memory & 1T HDD. It's been so long that I don't remember if the 1T HDD came pre-installed from Best Buy or the original crashed & I upgraded it.
