True, looking back through it, I think I misinterpreted it. I took the original idea to be "use the mode (UEFI vs BIOS) which was used for this current boot session". You can generate a grub.cfg for another system without needing to chroot. grub-mkconfig lets you redirect the output to any file you want. So, what's to prevent a user from booting a recovery CD and, without using chroot, using: grub-mkconfig -o /media/MyRealUbuntuPartition/boot/grub/grub.cfg > We're not going to support having both installed at the same time and > using the same config.

Furthermore, linux is what I turn to when I have trouble booting any of my partitions. If I can just get to a linux prompt, with fdisk/parted/grub/etc, then I can usually fix any other booting problems. So, it would be helpful to be able to boot a linux partition from BIOS mode if the EFI SP gets hosed. You can choose not to support that; that's your choice, but I think there are scenarios wherein it would be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024383 Title: update-grub generates only BIOS based menu entries for Windows, even on UEFI systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1024383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
