I think you should be able to boot linux directly by typing (I haven't tried this): grub> search --set=root --file /vmlinuz grub> echo $root ought to reply (hd0,gpt6) grub> linux /vmlinuz root=/dev/sda6 ro quiet grub> initrd /initrd.img grub> boot When the system is up and running, check and/or reinstall grub with: # grub-install /dev/sda You could then satisfy our curiosity by typing: # ls /sys/firmware/efi but you could also, having installed grub, check the contents listed by: # ls -lR /boot/efi/ It should look something like below, but with extra windows stuff. The file /boot/efi/EFI/debian/grub.cfg should contain something like: search.fs_uuid 12345678-abcd-9876-5432-abcdef123456 root hd0,gpt6 set prefix=($root)'/boot/grub' configfile $prefix/grub.cfg The listing: /boot/efi: total 1 drwx------ 3 512 May 19 2021 EFI /boot/efi/EFI: total 1 drwx------ 2 512 May 19 2021 debian /boot/efi/EFI/debian: total 3328 -rwx------ 1 108 Jul 29 15:33 BOOTX64.CSV -rwx------ 1 84176 Jul 29 15:33 fbx64.efi -rwx------ 1 126 Jul 29 15:33 grub.cfg -rwx------ 1 1549696 Jul 29 15:33 grubx64.efi -rwx------ 1 842104 Jul 29 15:33 mmx64.efi -rwx------ 1 930016 Jul 29 15:33 shimx64.efi Cheers, David.
