Windows did the equivalent of running efibootmgr and registered the
Windows bootmanager as first or only bootmanager present.
I wonder how we should treat dual or triple boot configurations
properly. Which kind of configuration do we treat as normal? Usually in
multi boot configurations you see Windows, a "normal" Linux and LFS. In
these cases one would usually add LFS to the GRUB config of the normal
linux. On BIOS you might also use GRUB to switch active partitions and
chainload individual GRUBs for LFS and the normal distro resp. Windows.
This is what I do on my notebooks where i frequently reinstall
On UEFI you could do the same: Add LFS to an existing GRUB. On the other
hand you could add an GRUBX64.EFI as LFSX64.EFI to the list of UEFI
bootloaders via efibootmgr. On a fresh machine with just LFS and no
other systems you would probably use the default /EFI/BOOT/BOOTX64.EFI.
In my opinion this is to much complexity. Thus I would recommend not
creating partitions for LFS, but in any case use a separate drive. This
might even be a 32GB USB thumb drive (should cost less than 15€), do a
clean install (thus not thinking about dual boot configurations). In the
end you have to pop up the boot selection menu and choose the drive to
boot from. This way we can provide a clean and usable configuration
without having to go too much to the details of dual and triple boot
configurations - which have many side effects especially when
chainloading on UEF.
