Hello alltogether,

for some time i was using Linux Mint 19.1 on my X200.
Now i wanted to update to 20. but i did not choose to update but to completely install the system new.

Now unfortunately i got stuck at the beginning and the system won't boot any more. I could install Mint 20 from USB flash drive succesfully, but after installing it gets stuck.

vmlinuz is not found, and also i don't have the hd0, but the partitions have other names. Does someone have any clue, how to proceed?
Please see the two screenshots.

Any help appreciated.

The linux command that you used expects to be followed by a path to a kernel file. That's why it keeps complaing "filename expected".

You have two partitions there, 1 and 5. One of them must have your kernel on it. To find out which, try ls (ahc10,msdos5) and see if you can find a boot directory on it. If so, ls (ahc10,msdos5)/boot should show you a kernel.

If not try the same thing with (ahci10,msdos1)

When you have a path to the kernel, pass that to the grub linux command. If you can get in, you can reconfigure grub with update-grub so that the path to the kernel is written into it for the future.

Hello and sorry for the late answer.
I searched for help in the chat channel from libreboot and someone helped me to update the BIOS to the newest version. This person also told me, that my grub.cfg seems to be screwed up, but now luckily everything is working fine. Unfortunately the exact reason i cannot tell. Maybe the new BIOS can deal better with broken grub files.
