Grub 2

Dealing with Grub 2

Here we go, another innovation that we neither need nor want.

You may (or may not) find this useful:

There are several important things to know about the new and improved (?) grub. One is that it numbers partitions differently than the old grub, but at this point I don't know if that means they start at one or zero. I guess if they change these things all the time, nobody is ever sure what is going on. All I can say is to watch out.

The second thing to know is that you don't just jump in and edit the file /boot/grub2/grub.cfg. I guess you could, but you will probably end up regretting it. Keep reading.

There are three places you need to look on disk that control what grub2 is doing:

/boot/grub2/grub.cfg - never edit this.
/etc/grub.d/* - a collection of scripts that you could edit.
/etc/default/grub - this is what you want to edit.

When you finish your editing, do this:

grub2-mkconfig -o /boot/grub2/grub.cfg

The usual thing I do is to edit the linux boot line to remove "rhgb" since I hate the red hat graphical boot and want to see what is going on when my systems boot.
