Well, as long as you're running Linux as well, I'll answer your question :-)

ARC does not number partitions the same way that Linux numbers disk
devices.  This may be at the root of your problem.  I've certainly been
bitten by this more than once.

I don't know the ARC rules for sure, but I think basically it counts the
primary partitions first, then the "logical drives" (subpartitions within
an extended partition).  The extended partition itself isn't counted.
Let's say you have your system partition as the primary partition,
the rest of the disk is contained in an extended partition, and the NT
partition is the third subpartition in the extended partition.  The NT
partition would then be sda7 to Linux, but partition 4 to ARC.

So try changing the partition number in the OSLOADPARTITION variable.
