Mastering Grub 2 The Easy Way

“Getting Grub2

“If you’ve messed with the original Grub (now called Grub
legacy), you doubtless know all about menu.lst. That was the file
where Grub legacy stored pretty much everything. In Grub2, the
closest equivalent is grub.cfg, also located in /boot/grub. One of
the most important differences, however, is that you should not
edit the grub.cfg file directly. Some of you may be thinking
“Ha! Warnings like that are for n00bs!”. Well the
reason for this rule is not because the developers don’t
think you’re l33t enough, it’s because that file is
auto-generated by Grub2 and will be overwritten without warning as
a result of things like kernel upgrades.”
