Package: grub-efi-amd64 Version: 2.02+dfsg1-4 Severity: wishlist Currently, you can have both grub-{pc,efi-amd64}-bin installed, but you can only have one or the other of grub-{pc,efi-amd64}, as the packages conflict with each other. This means that only one grub-install --target is supported in Debian's configuration framework at any one time.
(It is already possible to install both grub-*-bin packages and invoke grub-install with the desired --target manually, but this occurs outside of the Debian framework and so is not a good long-term solution.) I would like to request making it possible to install both packages simultaneously, with an appropriate configuration mechanism to disable one, both, or none. There are at least a couple of use cases I can see for this: 1. Assembling system images that can support both BIOS and EFI booting without needing to install/remove any packages to switch from one mode to the other; 2. A Debian install on e.g. a portable USB hard drive with a hybrid MBR/GPT partition table that supports *both* the BIOS and EFI boot paths.
