If you know one won't work, then there's no point in adding it. At update-grub time, you know if you are EFI and should search for an EFI bootable windows. It might be nice if you can detect that the windows install is only bios bootable and warn about the problem, but I'm not sure it's possible to get such a setup.
Last I heard, Windows can not be installed on GPT without EFI. If that is the case, then an EFI booting system can't have a bios booting windows install. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
