A recent security (?) update in 14.10 Utopic Unicorn caused "apt-get dist-upgrade" in Ubuntu 14.10 to try to remove package "grub-efi-amd64", and replace it with package "grub-pc". I use grub-efi to boot in UEFI mode, which at least originally was not compatible with the plain "grub-pc" without "grub-efi". Thus, I am a bit wary to remove the package "grub-efi-amd64", because it was quite difficult to set up the UEFI boot process, which I used because I was not able to install Ubuntu in BIOS mode without putting the hardware in legacy mode. So, my question is: Is it safe to replace the "grub-efi-amd64" with "grub-pc" so that the UEFI boot procedure still works? Note that I am unable to update the kernel without removing the "grub-efi-amd64" package, i.e. "sudo apt-get install linux-image-generic" also causes the removal of "grub-efi-amd64".
