[Discuss] Grub, EFI, Partitioning…

[Kent Borg]

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,
