My current desktop PC is an HP Pavilion that came pre-loaded with
Windows. I added Debian to it, but left the Windows stuff sitting
around just in case. The EFI partition is 256 MB, and the space is
used thus:
unicorn:~$ sudo sh -c 'du -sh /boot/efi/EFI/*'
1.2M /boot/efi/EFI/Boot
41M /boot/efi/EFI/HP
25M /boot/efi/EFI/Microsoft
5.1M /boot/efi/EFI/debian
I have no idea what the "HP" directory is for. Here's what's in the
next level down:
unicorn:~$ sudo ls -l /boot/efi/EFI/HP
total 12
drwx------ 5 root root 4096 Oct 13 2017 BIOS
drwx------ 2 root root 4096 Oct 13 2017 BIOSUpdate
drwx------ 2 root root 4096 Oct 13 2017 SystemDiags
So, obviously the size of the EFI partition is going to depend on what
you intend to put (or leave) in it.
