For what its worth, UEFI is what we're stuck with, all modern hardware uses it (and legacy boot is just a special UEFI bootloader). Intel plans to phase out the legacy bootloader in future releases of their chipsets as well, so it wouldn't hurt to learn how to use UEFI. -- Jonathan Billings <billings at negate.org>
