Description-en: GRand Unified Bootloader, version 2 (EFI-AMD64 version, signed)
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 built for use with the EFI-AMD64
architecture, signed with Canonical's UEFI signing key.
