Well... I've had this happen a few times, and I have been able to recover from
it with minor problems every time. You need to know at least the approximate
size and position of each partition for it to work. Just create the first one,
make it slightly larger than you had it before, and see if you can mount it.
Then adjust the size downward until you can mount the second, and so on. You
also need to know the types, eg if you try to make /dev/hda3 and ext2 partition,
when it was swap, it will not work. And don't use cfdisk, use plain fdisk- it's
quicker.
