Question

I am going to dual boot my Z580. Will the installation of GNU GRUB affect the BIOS?

Answer

GRUB doesn't do anything to the BIOS. It simply sits on the master boot record and lets you select what operating system you wish to boot into.

 

From WIkipedia:

 

'GNU GRUB (short for GNU GRand Unified Bootloader) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system's partitions."

 

GRUB sits on the master boot record but will not affect the BIOS - it lets the user select the Operating System s/he wishes to use.

Installing GRUB on GPT-format drives (UEFI BIOS systems) does not work.
