Do any of you quickly know what is needed to be modern
Linux boot partitions?
I have a /boot and a /boot/efi that Debain installed on
my internal SSD and I would like to duplicate them on an
external device. What do I need?
- partition as a GPT not MBR table
- format /boot with some Linux file system
- format /boot/efi with vfat
- copy files in
- install grub
…does that cover it?
Last I think I tried that my BIOS didn't want to boot
from it.
Thanks,

Boot should be ext4 as grub can read that file system type
on boot.
After installing grub you need to register the file
/boot/efi/EFI/debian/shimx64.efi with the efibootmgr. The
man page for efibootmgr gives good examples for how.
That last step should be done on the machine you intend to
boot from. If you skip that step then you have to boot
from the machine firmware menu.
If you do the grub install on the destination machine it
should do the efibootmgr step for you.
