I have a multiboot disk on which I have installed a number of bootable partitions, as wells numerous bootable ISOs on one partition. It took a long time to get configured and worked great up to a point. I had to install sysutils/grub2-efi to make it boot on all my laptops, some of which don't support long mode. It boots up OK on those. The ones that do support long mode, which I think are all uefi machines have a problem in that they are unable to boot into FreeBSD. When I select FreeBSD from the grub menu, I get a flashing cursor and the system hangs. I do not have this problem if I select a Linux system to boot.
This particular disk was able to boot all OSes on all systems at one point. The problem seems to have started when I installed Debian on another disk whilst both disks were attached, so I can only assume that Debian somehow 'touched' the EFI partition on my mutiboot disk. Is it possible that changes to the EFI partition could have made FreeBSD unbootable?
