Re: Copying one drive to a smaller one.
Booting UEFI requires different things: (detailed descriptions on
rodsbook site)
Proper subdir/entry in ESP (could be reused from old disk)
Proper entry in NVRAM (Can be read and changed with efibootmgr)
If i were you, i would prepare for emergency rescuing the system in case
of havoc. For example the refind iso is capable of booting a system
without a proper NVRAM entry, in order to rescue, i recommend preparing
such an iso.
Myself have been playing with different bootable systems using refind as
a boot manager, but AFAICT you won't need that part.
