I'm used to Gnome versions but thought I'd give the LXDE a spin and it's great!

Now onto my little problem...
Now, in the bulk standard version of Mint you can edit /boot/grub/menu.lst to change boot order and such things but there is no such file on LXDE (that I could find anyway)
I've searched the forum and nothing came up, surely this is a common enough question??
Any way if anyone has the answer as to where I can edit the grub menu that would be really appreciated.
TIA
KD.
