[SOLVED] ArchLinux doesn't start with CSM BIOS disabled

quellen · 2023-01-19 10:34:36

hello,
I would like to disable CSM option from the motherboard bios but if I do, Archlinux does not start (the bios menu appears when the pc is switched on).
Can I fix or do I have to reinstall Archlinux?

Read here: https://wiki.archlinux.org/title/Arch_boot_process
- This paragraph is particularly important
Disable CSM
(check for other CSM references around inside the UEFI Settings)
Boot into ArchLinux's ISO
Create ESP
(re)Install a UEFI-capable BootLoader

thanks.
Now on my SSD I only have a free partition of 1MB, could that be enough? i dont'use Windows.
On wiki it says it needs 2mb.
My SSD is a MBR partitioned disk.

It "should" be enough... Speaking of GRUB, its .efi loader's size is:

$ LC_ALL=C ls -lh /efi/EFI/ARCHLINUX
total 148K
-rwxr-xr-x 1 root root 148K Oct  8 21:51 grubx64.efi

It's just a "graphical thing"... It is nothing more than an indication that the output has reached the last line
