Black Screen, Acer Aspire A515-43 in Troubleshooting tools. I got Startup Repair couldn't repair pc.

I have an Acer Aspire A515-43 and it is Black Screen'ing. I've been trying many avenues to fix this. I tried using the Windows "Reset This PC" option. It looked like it was going to reset to from-the-factory condition, but it didn't. I tried the Windows Troubleshooting tools. I got "Startup Repair couldn't repair your PC".

I took out my Ubuntu on a Flash Drive device. I got Security Boot Fail. So I went to Supervisor Password, set a password. I did BIOS / Boot / Boot Mode / Secure Boot: Disabled. Now BIOS displays: Boot Menu: Secure Boot Disabled. But I still can't boot Ubuntu.

I don't have to boot into Ubuntu or install Ubuntu, I just want to get this laptop working, Windows would be fine.

At one point, in hopes that it would fix something, I upgraded this from Windows 10 to Windows 11. That did't fix the problem. Anyway, this is now a "barely works at all" Windows 11 Acer Aspire.

Please help me to get this working.

1. Do you mean it black screens after the BIOS Acer logo?
2. Did this happen suddenly for no apparent reason?
