Need help for INSTALL "grub-coreboot"


#1

Hi!

I want to install grub-coreboot in Ubuntu-Mate.

In Synaptic, when I mark to install ‘grub-coreboot’

To be removed:

grub-efi-amd64
grub-efi-amd64-signed
shm-signed

…shows me this:

Is it safe to install grub-coreboot?

Would my PC start after I installed coreboot and removed UEFI? Do I have to configure anything?
