Ciao ,
ho un problema con il dual boot su una macchina cosi ocnfigurata:
3 dischi di cui uno è SATA, sul primo disco c'e Gentoo (hda) sul secondo c'e Windows (dovrebbe essere hdb, è sullo stesso canale del primo ma in slave) e infine il 3° disco è in comune per i dati.
Ho configurato il mio grub.conf cosi:
Code:

default 0
timeout 20
splashimage=(hd0,0)/grub/splash.xpm.gz

title=Gentoo Linux
root(hd0,0)
kernel /boot/bzImage root=/dev/hda3

# Boot per Windows Xp
title=Windows Xp Professional
rootnoverify (hd1,0)
makeactive
chainloader +1


che c'e che non funziona ?

Ps: Gentoo parte senza problemi.

Tnx all

Se il dual boot è su due dischi differenti invece che su due partizioni differenti, non ci sono per caso delle opzioni da aggiungere in grub.conf?

Ma se nel BIOS imposti (presupponendo sia possibile) impostare il secondary master come primo disco di avvio, Windows si carica correttamente? Forse i dati di boot di Windows si sono corrotti (la butto lì :P )

Comunque il grub.conf che ti hanno consigliato dovrebbe essere apposto così!

ehm... piccola delucidazione, visto che winzozzo non è un sistema invasivo il problema è che generalmente predilige stare su una partizione primaria e sul disco principale... scommetto che se inverti l'ordince dei dischi, il tutto funziona, cioè se hda diventa winzoz e Gentoo diventa hdb va tutto :P

Io ho risolto così il mio problema era quello... 8O :D

P.S. il problema risiede nel loader del kernel di winzoz... cosa che si porta dietro da winzozzo 3.51 :P :P :P

Non conosco molto bene grub ma con lilo c'è la possibilità di rimappare l'odine dei dischi:

man lilo.conf wrote:

map-drive=<num>
Maps BIOS calls for the specified drive to the device code spec-
ified on the next line as to=<num>. This mapping is useful for
booting operating systems, such as DOS, from the second hard
drive. The following, swaps the C: and D: drives,

map-drive=0x80
to=0x81
map-drive=0x81
to=0x80


Vedi se trovi qualcosa di equivalente in grub.
