A long time ago, in a computer lab far far away, I stumbled upon a bootloader which dared to cross the boundaries between MBR and EFI.
It's name was Clover.
Using clover, you could boot any number of Operating systems that had previously been beyond your reach, simply because you didn't have that expensive new computer with a fancy UEFI BIOS.
Today, I am looking for the exact opposite. I have several MBR only OS's that I wish to install on UEFI only computers. Is there a way to do this that is as simple as Clover?
