So I've installed BURG, a fancy grub-like bootloader with more eye candy, on my Ubuntu 13.04 x64 box now and it wants to boot an EFI boot entry by default. Every time it does so I get thrown kernel panics and my system doesn't boot. I have to manually select the "normal" one in order to boot successfully. Personally, I don't have any use for the EFI entries and I don know how I got even them. Is there any way to remove these entries for good, even after an "sudo update-burg"?
