I'm having trouble installing on my Surface Pro (see this question) and I suspect that it is related to this recent bug fix on LaunchPad. The Surface is a UEFI based system, which might explain why GRUB fails to install.
How can I add the
grub-efi-amd64-signed packages to an ISO to test out this theory? I have tried checking out the branch with Bazaar and building it with
sudo ./congrego.sh but this fails with this error:
E: Cannot install into target '/media/elliot/d2/elementary/freya/tmp/amd64/chroot' mounted with noexec or nodev
