The effect of updating the bios via USB (possible only on windows) when all computers run on Linux.

All that tech for one bios update. Is it for a missile launcher? 😂

Removing the GPU...
Yes. you are indeed upgrading a BIOS.

Switch in old HDD,
Install windows,
Do bios upgrade,
Throw old HDD back in the pile.

What do you need all that other stuff for in this process?

@iamai lol it sure does look like it! I had to install windows in an old ThinkPad (the one on top of my desktop pc) to flash the bios into the USB thumb-drive after first trying in my other ThinkPad with an existing Windows VM. My server does not have a CD/DVD Drive, so USB was the only way.

@ArcaneEye the only “other” stuff are the two laptops. It looks like I am using all my computers because it is messy.

@magicMirror yes actually, I also did upgrade the CPU and ram, so i did not find it necessary to plug GPU before flashing the bios. After everything went well, I put everything back in.

Thinkpad firm upgrades can now be done on Linux as well. (see https://fwupd.org/lvfs/devices/ for supported hardware)

I see this and my brain just goes.
Mate, buy something.
One second later.
