Comment 8 for bug 806291

Very useful tool, I've used it in 2 different instances to fix boot issues on duel boot pc's one was a 32 bit and windows XP the other a 64 bit and Vista with a Lime tag-a-long. both machines contracted a rootkit that the av software could not remove from the mbr, but this little tool was able to rewrite the mbr making removal of the rest of the virus a snap.
 It should be noted for those new to Linux though that when you start Windows after using this tool it will run chkdisk on the windows partition, so don't panic.
