fstab is empty, I see no /boot/efi.
Did you udate Win11?

You can not use last snapshot from grub?

only Garuda Linux installed, I updated the system yesterday
I don’t have win11

Unfortunately, I don’t know how to use the last snapshot, how to do it

Search in garuda wiki.


Please follow the template and post garda-inxi from live ISO.

This is just from the live environment. First you need to chroot into your system.

garuda-chroot -a

Then run the command and post the output into the thread.

cat /etc/fstab

Try booting without this SD card plugged in.
