Hi deloptes,
It depends very much on the machine. I've just saved a machine that has
32 bit UEFI implementation and a 64 bit Atom processor. It's an Intel Baytrail
with a small amount of memory [2G] but required the Debian multi-arch .iso
to boot.
A later model of the same series - Lenovo Ideapad - does support 64 bit UEFI
and UEFI processor. Which machine do you have and what's the processor?
All the very best
Andy Cater
Which machine, which processor.
