Some notes on creating a disk image with Grub installed: 1. Create an empty disk image dd if=/dev/zero of=disk.img bs=1M count=32 2. Create one primary partition cfdisk -h 16 -s 63 disk.img 3. Set up a loop device sudo losetup -f disk.img 4. Set up loop devices per partitions sudo partx -a /dev/loop0 5. Create the ext2 filesystem sudo mkfs.ext2 -L root /dev/loop0p1 6. Mount the filesystem mount /dev/loop0p1 /mnt 7. Extract the root filesystem sudo tar -C /mnt -xf output/images/rootfs.tar 8. Unmount the filesystem, clean up loop device sudo umount /mnt sudo partx -d /dev/loop0 sudo losetup -d /dev/loop0 9. Install grub output/host/sbin/grub --device-map=/dev/null and in the grub shell, enter: device (hd0) disk.img geometry (hd0) <cylinders> 16 63 root (hd0,0) setup (hd0) 10.
