In this case it survives thru the first restart..
So disk geometry must be right at the first restart.
Then, something is probably changing disk geometry in the 'active' partition.
On the second restart it is not right anymore..

Troubleshooting this one is not easy..

But:

Pay attention to what is written to the console at startup.
It will tell you what numbers of heads and sectors the legacy BIOS think the 
disk geometry should be.

If you dont override the 
    fix_disk_geo_heads = 
    fix_disk_geo_sectors = 
settings in unattend.txt the 'legacy BIOS' heads/sectors will be written into 
the 'active' partition.
please see 
http://ubertechnique.com/unattended/nt5xinstall
for the details on how disk geo fixing is done.


In addition there will be a file with the generated disk geometry 
(when using nt5x-install):
/c/netinst/partgeo.bin
Its a binary file, only 4 bytes long.
byte:
1 : sectors
2 : should be zero
3 : heads 
4 : should be zero
It can be inspected by booting Knoppix.

Se also the top of nt5x-install for the details.
