Install fails when attempting to install efi partition code

[Andrew Pols]

Installer strongly demanded creation of EFI partition on a system which does not have UEFI support.

Creation of EFI partition performed manually along with separate root partition and home partition on second drive.

Installer failed when attempting to install boot code on the EFI partition.
