I have a gigabyte motherboard that has EFI technology, and right now windows 7 and Ubuntu 12.10 (both 64 bit) boot fine. There is an update for my bios to enable UEFI technology. If I upgraded, would Ubuntu still bot alright and if not, what would I have to do (Even if it means reinstalling the OS). Thanks in advanced.
