[Bug 1767703] Re: Calling 'apt-install grub-efi-amd64-signed' failed

[Graham Mitchell]

There are some edge cases when the user's disk is partitioned to boot in
bios mode, but the EFI mode installer doesn't detect it.

There is supposed to be a warning message about this combination but it
does not always show up -- as evidenced by this thread.

For these users, there is NO indication that something is wrong until
the very end, when 'apt-install grub-efi-amd64-signed' fails, but by
then it is too late.

Many people have lost data because of this bug.

Is there an existing bug report for "EFI mode installer doesn't always
detect when booted in BIOS mode"? If so then maybe this bug can be
marked as a duplicate of that one.

But this bug should not be closed as invalid until then.
