---------------------------------Show     partitions (Help) -----------

With this menu you can see your partitions without
modifying them.

This is useful to see how a disk is treated from
Grub point of view (Is it /dev/sdb your first or 
your second hard disk? You might know the answer here.

Do not trust in /dev/sdb notation just trust
in: (hd0,1) one. (The GRUB notation)

hd0 => 1st hard disk
1 => 2nd partition

Just select one (PRESS ENTER) of the partitions 
and you will come back to this menu back again.
