Control: merge -1 821340 Control: reassign 821340 partman-efi Control: retitle 821340 partman-efi: add extra warning about preferring GPT for USE installation
Hi Josh, I'm merging this with your other bug report - they're clearly the same issue.

Again, it should be possible to do this (select GPT) using expert mode rather than having to restart. Maybe we should add a warning during partman-efi setup that some machines won't boot in MBR mode, and offer to switch. This is clearly difficult to do in some cases, e.g. if other OSes are on the system already. -- Steve McIntyre, Cambridge, UK.
