I don't know of a "all in one" utility off the top of my head, I've always
either done dump or more likely tar of the files. Then on bare metal
recovery, you just boot into a rescue CD, make the partitions and filesystems,
untar, reinstall the boot loader, reboot.
Instead of tar or dump, you can use dd to image the entire drive,
including its partition table and boot sector, or an individual
partition. Similarly Partimage (http://partimage.org/) will let you save
a partition to a file with the added benefit that it intelligently skips
over unused space.
As above, you'll need to bootable rescue CD, such as SystemRescueCd
(http://www.sysresccd.org/), in order to restore partitions on an
unbootable system.
Try reposting your query on the BLU (www.blu.org) discuss list, as
you'll find a larger population of Linux users there.
