    Using mc as a visual shell, I was able to copy the entries for the sda
    devices from /dev (regular install) over to /mnt/sysimage/dev and then
    running the fdisk command showed the information regarding /dev/sda.
    This might be danerous to attempt to create (actually copy the node to
    the chroot via the regular installation.)

    Running grub-install /dev/sda yielded the below output in my chrooted
    usb installation.

    This worked for me, but I cannot boot this installation anyway.
