Hi.
So you're trying to install Grub to the flash drive, right?
What are you booting the virtual machine off of?
Did you dd an iso image to the thumb drive? (trying to pinpoint this iso9660
filesystem)
First, the iso9660 filesystem is read-only. So you're not going to be able to
put grub modules and a grub.cfg on that filesystem (unless you rebuild it).
Second, is all of the thumb drive formatted as iso9660, or is one partition of
the thumb drive formatted as iso9660? Or is there no iso9660 filesystem on the
thumb drive? In other words, do you mount /dev/sda or do you mount /dev/sda1?
If you're just mounting /dev/sda, there's no MBR or space after the MBR, both
of which Grub needs, unless there is a BIOS boot partition in the case of GPT.
If you dded an iso over the whole thumb drive, there's no MBR or that space
afterwards. If you dded an iso over a partition of the thumb drive, there
should still be an MBR and the space afterwards.
Are you booting the virtual machine with an iso, the thumb drive, or what? You
could just boot the virtual machine off the iso, nuke the thumb drive, and
install Linux to it. You don't even need to do that super VirtualBox shortcut
to the thumb drive raw vmdk thing. You can just share it as a USB filter.
