Unfortunately I’m unable to boot my linux system anymore.
My small NUC is complaining that there is no bootable disk available. This happens after a BIOS upgrade.
Looking into the BIOS I changed the boot setting from UEFI to the old MBR.
I have booted now with “Tumbleweed Installer Stick -> more -> boot a Linux system” into my system (works fine) and played around with the yast-> bootloader.
My current configuration is:
write in master Boot Record
set activ flag in partions table
my disc looks like this:
Model: CT500P1SSD8 (nvme)
Disk /dev/nvme0n1: 500GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: pmbr_boot
Number Start End Size File system Name Flags
1 1049kB 9437kB 8389kB boot, legacy_boot, esp
2 9437kB 107GB 107GB btrfs
3 107GB 110GB 2147MB linux-swap(v1) swap
4 110GB 500GB 391GB xfs
Part 2 is my / partition
Part 4 my /home partition
no separate /boot partition .
To be honest, I don’t know what to do.For two days I have tried all possible combinations, but unfortunately without success.
That would mean the update changed it from MBR to UEFI. Rather strange.
I asked because you said you changed from UEFI to MBR, but did not explain if that was because you thought it was earlier the case, or just a trial out of despair. And also because of the existence of nvme0n1p1 of which parted has not much to tell. Could it be an EFI partition? Maybe more information from
Shortly before the reinstallation, I found the solution.
I had an EFI system. I wasn’t aware of. If something is running you don’t look at it.
So I formatted the 8Mb partition as an EFI partition with FAT and mounted it under /boot/efi. I had not done that before!
Then reinstalled grup2-efi and booted.
It works. I am pleased.
Thanks for your help!
Why this happend after a BIOS update? I don’t have a clue
