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.
