Uso da poco ubuntu 7.04 ho linux su un hark-disk e windows su un altro.
Sapete che file devo modificare per avere all'accensione del pc il bual-boot? una volta già ho provato ma non mi fa modificare il file come devo fare?

apri un terminale (che mi pare stia in strumenti-accessori) e digiti
sudo gedit /boot/grub/menu.lst
premi invio
digiti la password (non ti preoccupare se mentre scrivi non si vede nulla)
premi invio
Poi metti qui il contenuto del file e ti diciamo come modificarlo.
Intanto dicci in che partizione sta xp (la prima la seconda la terza)

Prova ad aggiungere in fondo queste righe

salvi esci e riavvii. Ovviamente per aprire il file devi ridare il comando che ti ho detto sopra. Gia che ci siamo te lo spiego:
sudo: serve per acquisire i privilegi di amministratore, senza i quali non potresti modificare importanti file di sistema
gedit: è il nome del programma di scrittura, avresti potuto usarne altri, ma per comodità ti ho messo quello predefinito di ubuntu
/boot/grub/menu.lst: è il percorso del file da aprire con il programma scritto prima, quindi gedit.

sarebbe utile conoscere la tabella delle partizioni degli hd, altrimenti giochiamo agli indovinelli. (hd1,0) è utile se windows si trova sulla prima partizione del secondo hd, ma noi non lo sappiamo.
Posta il risultato di questo comando
sudo fdisk -l
e se puoi indicaci dove hai windows.

si in effetti ho dato per scontato che stesse sulla prima partizione del secondo, ma nessuno dice che è così :D
