installing Grub

lantech19446

So in the lesson there's very little mention of installing Grub they mention configuring grub and basically everything they tell you is followed by but you should never ever do this by hand. Grub2 is accompanied by one command to install it sudo grub2-install /dev/sda followed by this note of yep there's a lot of flags that need to be set in addition to this and messing it up will mess up your whole system, Grub1 is simpler but still requires a litany of editing. I didn't pay much attention with the install instructions because there were so many things saying don't do this that it seemed like it was just being covered out of prudence so I guess my questions are as follows.

1. Do I actually need to know how to perform this for the exam

2. How on earth can I practice doing this???
