I basically unmounted swap, stole 100M from the 4G partition, remounted swap, and then dd'd the /boot/boot1.efifat file to the new small partition. rebooted and all came up. I was doing this from the latest stable though. Just make sure you have performed a "svnup stable" in the last few days and done a source upgrade and you should be good. It is possible to convert a MBR layout to GPT, but it does require downtime and backup as if you get it wrong you could easily loose your partitions On 3 February 2016 at 21:34, Bob Willcox wrote: > Is there a way to convert a system from legacy boot to UEFI boot?
