Is it possible to use the
dd command to create a bootable ISO image? I use the following command to do it:
dd if=/dev/sda of=/mnt/sdb/my.iso
I am able to create ISO, however I am not able to boot with it. When I try to boot, I get this error:
Operating System not found.
/dev/sda lists 4 partitions and in partition 1, grub is installed: filesystem is ext3.
