grub-efi-amd64-bin - 2.02+dfsg1-4pureos1 main

GRUB is a portable, powerful bootloader. This version of GRUB is based on a
cleaner design than its predecessors, and provides the following new features:
.
- Scripting in grub.cfg using BASH-like syntax.
- Support for modern partition maps such as GPT.
- Modular generation of grub.cfg via update-grub. Packages providing GRUB
add-ons can plug in their own script rules and trigger updates by invoking
update-grub.
.
This package contains a version of GRUB that has been built for use with
EFI-AMD64 architecture, such as the one provided by Intel Macs (that is, unless
a BIOS interface has been activated). It will not automatically install
GRUB as the active boot loader, nor will it automatically update grub.cfg
on upgrade, so most people should install grub-efi-amd64 instead.
