Cannot select grub partition for booting in BIOS, but can access it from boot menu

Thanks, here you are

That seems OK.

The logical next step is to set the Manjaro UEFI boot loader as default in your BIOS. If it’s missing, then as @teo suggests;

@Teo

Reinstall grub as per wiki.

which should (in theory) add the UEFI entry again; then set that as the default.

Not sure, please help me. Isn’t nvme1n1p1 nvme1n1p1 my only ESP? KDE Partition Manger says, that 1n1p2 is Windows Reserved.

Should I just reinstall grup and see if that fixes it?

Just confirming that you only have one $ESP according to the lsblk output earlier; as it should be:

├─nvme1n1p1 vfat   FAT32 ESP  72F3-E0A4  195,7M  24% /boot/efi

So, yes, reinstall GRUB as indicated in the Wiki article (linked above). Let us know how you go.

Regards.

I have added a few links (following) which might be handy to bookmark in case they might ever be needed, but they are not directly related to this issue.

• Create a Ventoy USB to launch Manjaro (and other) ISOs

@Argumon

might that be an issue with that specific BIOS (upgraded to the latest available)

Check the manufacturer website and make sure it’s not a beta BIOS that you installed – the latest non-beta BIOS is always preferable.

Also double check that your BIOS settings are as needed for a UEFI booting system. Remember, with a new BIOS all those settings revert to the defaults. You would need to again disable Secure Boot, etc.
