Motherboard stopped working

Yes, you can save settings onto a USB flash drive if memory serves. It is only valid
for the particular BIOS version it was saved from however so it's no good if you
are updating your BIOS. Generally it's a waste of time unless your BIOS settings
are exceedingly intricate (memory timings, voltages, per core overclocks etc).

As for cleaning the socket, it isn't recommended to mess with LGA sockets.
It should be fine as is. Some canned air won't hurt. Just be sure to keep the
nozzle at least 20cm from the socket so the pressure doesn't bend anything.

Awesome, glad to see you up and running again.

Windows Boot Manager is added by windows during install, the second is added by
the board on first boot. Because you installed the OS on the old board it didn't
create a duplicate. It's nothing to worry about. Just use the Windows boot manager one.
It shouldn't make a difference but if windows set any flags on boot they will be
missing on the second option.

Enjoy

Everything works but I'm confused & it's probably my old brain.

It seems Windows Boot Manager should always be there. However my notes from the original install say there was only "Boot Option #1 - M2_1: Samsung SSD 970..."

If "the second is added by the board on first boot", isn't that the opposite of "Because you installed the OS on the old board it didn't create a duplicate"?

Am I getting things mixed up regarding which one is the duplicate?

I installed Windows 10 only once on the SSD. Could one of the "Feature" updates created a second boot option?

I'm just curious what is happening.

Thanks again
