@SatPhil: "sudo efibootmgr -v" was not recognized as a command for me, but I used two other methods that I think answer your question. See below:

ubuntu@ubuntu:~$ [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
BIOS
ubuntu@ubuntu:~$ dmesg | grep "EFI v"
ubuntu@ubuntu:~$

The second method ("dmesg | grep "EFI v"") didn't return any information, so that looks like I have BIOS instead of EFI/UEFI. Does that answer your question?

@tsikerdekis: Your earlier post referred to a link that no longer works. Any other link I can read explaining the steps you took? If not, what specific "deb" (Debian, I assume) packages should I download for grub2?
