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.
