Re: grub-install Cannot find a GRUB drive for /dev/sdXY
Hi Andrei, thanks for your reply. I tried both /dev/sda and /dev/sda2. I ended up solving the problem by making a total of three partitions: A small one for EFI, another one for /boot, and the encrypted main partition. Small snag was that the Debian installer cannot be persuaded to install the grub EFI into the EFI partition on the mobile disk but on the one in the built-in disk. But that was easily fixed by by mounting the mobile EFI partition, correcting /sys/fstab and re-installing grub and kernel.

Hope this helps, Andrei

grub-install Cannot find a GRUB drive for /dev/sdXY
Hello, I somehow managed to screw up my /boot partition. Now I'm trying to re-install it by booting from a Debian installer stick. After network configuration, I do this: 1) Mount the root partition at / 2) # for s in dev sys proc; do mount --bind /$s /mnt/$s; done 3) # mount --bind /etc/resolv.conf /mnt/etc/resolv.conf 4) # chroot /mnt 5) mount /dev/sda2 /boot Now I'm in my "full" Debian system. Next: # grub-install /dev/sda2 # apt install [linux kernel] # update-grub Error: Cannot find GRUB drive for /dev/sda2 I tried both the grub-pc as well as the grub-efi versions. I don't really know what the difference is and how it works, but with EFI I get a similar error (something like EFI directory not found) BTW /dev/sda is an external SSD connected via USB3. I've been using this setup for years to boot my employer's company Windows laptop as my private Linux machine (not touching the internal SSD at all). It stopped working from one day to the next, no idea why. I've searched the Internet up and down for the error message, but I couldn't find anything useful.
