The debian boot entry number 0009 is not in BootOrder, no wonder why it 
does not boot automatically. grub-install updates BootOrder to make the 
debian entry first unless --no-nvram is passed, so something is wrong here.

Weird, Debian and Ubuntu EFI partitions have the same partition GUID 
(PARTUUID) but different sizes.

There are two different SSDs, 2TB Western Digital and 512GB Samsung.

The EFI partition is very small. It is big enough for GRUB but not for 
systemd-boot.
