You haven't gotten the point of the question. GRUB is in the MBR from the install. It has a location to get to the GRUB directory to load stage1 (we know that stage1 and stage2 and all other things are in the GRUB directory look them up yourself). So it locates the GRUB directory to load stage1 then why would it now lose that location to load stage2. > > - -- > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.2.2 (GNU/Linux) > > iD8DBQE/LRZ70iMVcrivHFQRAmf+AJ4qbjgdK+3rpvdCsXgz47rIeh6SPgCfQlWU > sYhitwThMNCKrXCfpgBk1kU= > =kcXm > -----END PGP SIGNATURE----- > > > -- > redhat-list mailing list > unsubscribe mailto:[EMAIL PROTECTED] > https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
