That caused an error in the Grub Customizer.

I wiped the disk and installed MX 21.

Did installing mx-21 fix your problem?

No, but someone recommended reinstalling/recreating Grub. Will do that later today.

Post the output of ls /boot/grub

colorpurple21859 · 10-23-2021, 03:03 PM

Open a terminal

Code:

 sudo apt-get install grub-efi
sudo apt-get install efibootmgr
sudo mkdir /boot/efi
sudo mount /dev/nvme0n1p2 /boot/efi
sudo grub-install --target=x86_64-efi

Ignore error message about efivars
Reboot, use f12 key to see if there is an option to boot mx efi mode, if not an option to boot from a file and look for a grubx64.efi file.
Once booted rerun sudo grub-install and update-grub

No boot option, bid find that file in File System.

sudo grub-install
gives me
Installing for i386-pc platform.
grub-install: error: install device isn't specified.

You won’t get that message with

Code:

sudo grub-install  --target=x86_64-efi

I am getting
grub-install: error: cannot find a GRUB drive for —taget=x86_64-efi. Check your device.map.

You have to run all of these after a reboot
for it to work

Code:

 sudo mkdir /boot/efi
sudo mount /dev/nvme0n1p2 /boot/efi
sudo grub-install --target=x86_64-efi

Thanks for putting up with this!

After reboot and pasting that, I get:

mkdir: cannot create directory ‘/boot/efi’: File exists
mount: /boot/efi: wrong fs type, bad option, bad superblock on /dev/nvme0n1p2, missing codepage or helper program, or other error.
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
