| 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. Image is ready |
| Can be tested in Qemu, with: |
| qemu-system-{i386,x86-64} -hda disk.img |
