RE: [bug #4245] Copying a hard drive and making the copy bootable is hard

[Treutwein Bernhard]

Oops, if both hds are of same type, why don't you use

        dd if=/dev/hda of=/dev/hdb bs=512

if they are not exactly the same, you could use partimage.
(you might have to boot from a CD based distribution, e.g.
Knoppix), see www.partimage.org.
