Just saved the bootcode from Sector 1 und 13 and replace it after
formating the drive with the help of "dd":
dd if=/way/to/ntldrbootcodesector0 of=/dev/hda1 bs=1 count=420 seek=90
dd if=/way/to/ntldrbootcodesector12 of=/dev/hda1 bs=512 count=1 seek=12

If I install windows directly the heads and sektors in the fat32
partition shows up 255/63. But If you want I can send you the different
boot sectors from the fat partion and the mbr. Maybe you have more
expirience than me....
At least I only modify the heads/sektors but not the cylinders. Maybe
thats one reason???

The project: http://sourceforge.net/projects/unattended has reported
this bug I thought, because here:
"The parted mailing list has already been informed about this problem"
There is also a short report and solution about this problem.
I thought you had heared about that project.... I am working on the
project unattended-gui (http://sourceforge.net/projects/unattended-gui)
which is able for example to install Windows and various Linux
"unattended". But while the unattended project doesnt seems to develop the
boot disk any more we decided to make our own.... And we want (and do it) to
use parted inside this boot disk ;-)
Maybe it will be possible in the future to give parted the same options
-C cyls Specify the number of cylinders of the disk. I have no idea why
anybody would want to do so.
-H heads Specify the number of heads of the disk. (Not the physical num
ber, of course, but the number used for partition tables.) Reasonable
values are 255 and 16.
-S sects Specify the number of sectors per track of the disk. (Not
the physical number, of course, but the number used for partition
tables.) A reasonable value is 63.
I thought you were also the project leader of fdsik? Or am i wrong?
BTW: excuse my bad english, I hope you understand what I mean....
