Hi Josh, It depends very much on the machine involved, to be honest - many will boot UEFI from appropriately partitioned MBR-partitioned disks. It depends very much on the firmware of the machine here. d-i deliberately will not *by default* change partition type. If you do need to do this, expert mode should let you do it anyway. -- Steve McIntyre, Cambridge, UK. st...@einval.com < sladen> I actually stayed in a hotel and arrived to find a post-it note stuck to the mini-bar saying "Paul: This fridge and fittings are the correct way around and do not need altering"
