If you are re-installing Windows in between the saving and restoration
of the boot sector, or are moving the files, i.e. ntldr.dll or what it
is called, around, this is the cause.

The geometry components have to fit.  From what you wrote in an earlier
mail, I gather this particular hard disk has 80 GB.  If you change only
one component and don't adapt the others (or two without fitting),
you will get problems.

I can't remember this, but maybe it was in the times when I wasn't
maintainer of GNU Parted yet.  I'm currently looking into the changes
of 1.6.23 to find the problem.

Doesn't it work for you?

I am the maintainer of GNU fdisk, a clone of util-linux *fdisk that uses
libparted.  GNU fdisk has the -C option, but it cannot create file
systems ATM.

  GNU fdisk is beta software right now.
