If you are running FAI 3.4.8 or some experimental version, you might want to add
the align-at option to your disk_config line, which would then be

disk_config disk1 preserve_always:1 bootable:1 align-at:8225280B

to enforce a cylinder-alignment of your non-preserved partitions. Furthermore,
may I ask you to provide a full debug log of setup-storage? To obtain this, you
would need to add export debug=1 to some of your class/*.var files and then
fetch the /tmp/fai/format.log file from your installing client.

I'm still pretty puzzled about this problem. I'm short of asking you to hex dump
your master boot record. The only option I do see, and please excuse for asking
about this: are you really sure that the partition is ultimately corrupted and
that it isn't Win 7 saying that it just has to run chkdsk once, but will run
fine afterwards?

Hmm, maybe Windows 7 stores additional information in the MBR? Would you be able
to follow the recovery advice given here:
