Ho trovato una guida che mi ha fatto superare il problema del fallimento di chroot a questo indirizzo:
http://www.bufferoverflow.it/2010/04...ub2-su-ubuntu/
ma nonostante ciò ho riscontrato un errore che riporto, passaggio per passaggio (in grassetto i miei comandi):

Il fatto che non trova la lista delle partizioni si ripete almeno un paio di volte nell'ultimo comando. Come posso risolvere questo problema?
