Re: Can I password protect individual operating system entries?

[James Lott]

I think the "correct" solution for something like this would be disk 
encryption on the partitions/disks containing the OS you want to 
protect. Otherwise, someone who has access to boot into the unprotected 
OS (or some other protected OS) could still access the protected OS; all 
they would need is the proper filesystem drivers.
