[Erlug] menù di grub non appare...

[iw4blg [Permanent Link]]

Ciao a tutti, 

sul mio PC ho una Ubuntu 10.04 e il grub 2.
Al boot, avvia direttamente l'OS di deafult senza farmi apparire il menù
di scelta.. che poi di scelte ci sarebbero solo il modo d'emergenza ed i
test delal RAM.. cmq sia, lo vorrei vedere..
Ho controllato varie impostazioni, ma non ho trovato nulla che mi
spieghi..
Di seguito metto il mio grub.cfg che "riassume" nel suo linguaggio le
varie impsotazioni se ben capisco..
Mi potete aiutare voi a capire?
Grazie!
Pierluigi
