Not really. It makes obvious what is already known: if someone has
physical access to a machine, they have a huge amount of power. If
they want, they can even replace the hard drive, or take a byte-by-
byte copy and analyse it later.

Likewise, if they have suitable privileges on another OS on the same
machine [1], they can get raw access to any drive on the machine.

There are really only three answers to this:

 * Don't let anyone untrusted have physical access to sensitive
   computers.

 * On multi-boot machines, you need to keep security tight for ALL OSes.

 * Encrypt sensitive data, and ensure that the key is not stored on the
   computer. This probably also implies having encrypted swap.

I'm sorry I can't help you with your main problem: I don't know 
Partition Commander. It's possible that Partition Commander has made
unwarranted assumptions: it sees grub the package, and assumes you'll
want to use it to boot.
