      If nothing else you get to move to GPT partitioning. I don't know if its the norm but my old bios refused to boot GPT-formatted partitions, it only understood MS-DOS partition tables
      All opinions are my own not those of my employer if you know who they are.

        Thats wrong, you can force install grub into protective mbr. GPT does not use the first sector so it can be reused, by default 1 partiton with disk size is created as protective mbr.

          I'm not saying it was -right-, just that I couldn't get it to -work.- But then again my last system was an OEM Dell made before EFI/UEFI/GPT were really a thing, so there's quite a few possibilities as to why.

            GPT is optional with EFI, a primary MBR fat32 works as well. But those details are unknown for most ppl.

              I have an old HP server from the XP days that can accept GPT partitioning on BIOS. Interesting. Initially used it for Citrix XenServer, then eventually turned it into a Fedora / Windows box and gave it away.

                The one and only problem is BIOS access for HD bigger than 2 TB. You could use a boot partition in the first 2 TB, but can be tricky, i would use that only with EFI.

You then need to go into the UEFI configuration menu before you're able to boot back to Linux. On my particular system that I've tried it on, more than 50% of the time the UEFI lost the GRUB option in the process of Windows re-registering itself, requiring a recovery boot to reinstall GRUB.
                  Definitely a bug, a well-behaved system won't do that. Some systems are hardcoded to boot the windows loader by filename, and the workaround is to overwrite the windows loader in EFI. On my ASUS UX31 I didn't bother with grub, instead using EFI stub and efibootmgr to boot directly from UEFI to my kernel.

                    Are you suggesting Windows is a well-behaving system?
