Windows 10: Windows 10 installation failed with no error code.

I am currently trying to upgrade my computer from Windows 8.1 to Windows 10, However, after at least four tries of getting this thing to work, which each of those being a consistent failure, I have decided to ask the forums here for help.P.S. My computer currently fits all of the specifications required for upgrading to Windows 10.

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!
