I need to restore GRUB bootloader on EFI partition:
As you can see, it’s on GPT partition table, is fat32 and has boot, esp flags. It doesn’t right mount yet, because I recreated it anew.
The weird problems I am facing is that when chrooting, I get error with mounting it (I got it right from the start, so even before recreating it):
sudo manjaro-chroot -a ✔ 14m 0s
grub-probe: error: cannot find a GRUB drive for /dev/sdd1. Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sdd1. Check your device.map.
==> Mounting (ManjaroLinux) [/dev/sda2]
--> mount: [/mnt]
When I try restore EFI bootloader:
[manjaro /]# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
Installing for x86_64-efi platform.
grub-install: error: /boot/efi doesn't look like an EFI partition.
The check of this partition alone in Gparted results in error.
I found such old info:
I cannot do:
[manjaro /]# grub-mkdevicemap
bash: grub-mkdevicemap: command not found
The advice is to write my own map:
just write your own
/boot/grub/device.mapfile. In your case, its contents could be just(hd0) /dev/sda(Ideally, you would use an appropriate
/dev/disk/by-id/...pathname in place of/dev/sda, but that’s not mandatory.)
When I tried to create that file I got:
[manjaro /]# nano /boot/grub/device.map
Error in /root/.nanorc on line 1: Error expanding /usr/share/nano-syntax-highlighting/*.nanorc: No such file or directory
Remember, I’m still in Manjaro Live chrooted, but without proper mount.
So I tried exiting chroot and mounting manually:
sudo fdisk -l /dev/sda ✔

Adding boot menu entry for UEFI Firmware Settings ...
Looks, like there’s been errors, basically one main error from the beginning…
Checking further:
[manjaro /]# ls /sys/firmware/efi
config_table efivars esrt fw_platform_size fw_vendor runtime runtime-map systab
Is that OK? Looks all right.
Ok, next steps are:
[manjaro /]# exit
exit
[manjaro manjaro]# modprobe efivarfs
[manjaro manjaro]# manjaro-chroot /mnt /bin/bash
[manjaro /]# mount -t efivarfs efivarfs /sys/firmware/efi/efivars
[manjaro /]# ls /sys/firmware/efi
config_table efivars esrt fw_platform_size fw_vendor runtime runtime-map systab
No errors at this point. I’m afraid, the system still won’t boot correctly because of the:
cannot find a GRUB drive for /dev/sdd1.
I have no idea, what is GRUB driver? Isn’t it the whole EFI partition?
OK, going to reboot, as that is all I could do, following those instructions. Fingers crossed.
