[RISOLTO] avviare pendrive da grub2

[nik57]

ho la necessità di avviare diverse pendrive da grub2 senza dover ogni volta modificare il bios
ho provato 

Codice:

menuentry "-   Pendrive_2" {
set root=(hd2,1)
chainloader +1
}

menuentry "- Pendrive" {
set root=(hd1,1)
chainloader +1
}

 ma nulla...
....disco "hd1,1" (o hd1,2 o hd2,1 ...) non trovato

questo lo fdisk con due pendrive collegate... 

Codice:
