I've got that T-shirt! :(  It's frustrating, isn't it? Even if you think
you might understand it, there's no way (that I've found) to see what
commands are actually going to be executed. And there are so many
different menus/buttons scattered around that screen, you have no
confidence in how they might interact.

I just abandoned the whole GUI idea and went back to the command line.
Even then you have to be very careful about the device map and about
which kernel is running whilst you do things.

Step 1 is to read the grub manual!

Well /boot is used by grub. So the whole concept of mount is irrelevant.
You need to have a *consistent* set of whatever files grub needs to boot
your system.

Which documentation? (hd0,5) is the *second* extended partition - see
http://www.gnu.org/software/grub/manual/html_node/Naming-convention.html

Grub's 'find' command is very useful for confirming what it thinks the
partition is called - http://www.gnu.org/software/grub/manual/grub.html#find
But again, be very careful of the device map.
