Hi,
it was the first time for me to have a computer death simply by modifying BIOS changes (no firmware update). I installed a new Samsung NVMe HD, copied the system from the old SSD on it with Samsung Magician (yes it can copy an old bootable system to a new HD, was new for me too). Then I wanted to create a multiboot system Win - Linux with grub, this didn't work so I modified some BIOS settings (TPM, trusted platform module, CSM, boot order etc.). It didn't work as expected, so I decided to use the old HD for vm images.
After a reboot I changed the BIOS settings back (assume, problem was that I did not create new keys for TPM or something like this). Reboot - and NOTHING worked, except fan. No BIOS, nothing.
Long story, short result:
The BIOS was dead and after a long while of rtfm I found the solution for the Gigabyte mainboard that I have never seen before (and I thought I know them all):
Download the BIOS from internet, copy it on an empty USB-stick and rename it GIGABYTE.bin (this was hard to find).
Then switch OFF the machine, do not remove power cable and do not switch off the power switch on the back side of power supply, plug the stick into a SPECIAL PREPARED USB port (see manual). Gigabyte has a mini switch on the mainboard, press it and it updates the firmware without Win/Linux/DOS and no GUI. The only thing you can see is a blinking LED on the mainboard. Wait, and after a few minutes everything works again.

Sorry for this off topic article, but I hope it can help any hobbyist out there.
