Well it is really weird that 64 bit is not the recommended version as you can not boot 32 bit on all systems sold with Win8 preinstalled without enabling the CSM (Secure Boot is basically impossible with CSM enabled, but there are motherboards which support that for legacy gfx cards - you need GOP mode for pure UEFI). So when you want to boot in UEFI mode then this will only work with 64 bit. Hard to recommend 32 bit in those times There are only some 32 bit UEFI Atoms which can not use 64 bit, Intel made a huge mistake to buy 3rd party graphics without working 64 bit drivers, but thats why this exists. I would never buy this crap for Linux.
No announcement yet.
Ubuntu Is Close To Recommending 64-Bit By Default
