I believe I have found my own solution.

I have just altered the Extension Attribute script that looks for the Recovery Partition, to search for our Windows drive name instead.

I believe you could also simply specify search criteria as:

OS Configuration Information -> Operating System -> not like OS X

Hey Matt,

Chiming in a bit late here, but back in like 2008 or 2009 I deployed Windows to a ton of Macs. They were a dual boot configuration. We had to have Windows and a dual boot config to run a specific application, so I used a dummy receipt system (this was pre Extension Attributes) to track if they had an NTFS partition or not. Then I could scope saved searches by if they had the dummy receipt or not.

I just used the `df` command. You could do something similar, here is my example (note I don't have a NTFS system available):

df -T hfs
Filesystem   512-blocks      Used Available Capacity  Mounted on
/dev/disk0s2  975093952 232630808 741951144    24%    /
/dev/disk1s1     204720    147456     57264    73%    /Volumes/Casper Suite SDK - November 2011
/dev/disk2s1     204720     95288    109432    47%    /Volumes/Resource Kit - November 2011

So, if you did a df -T ntfs it should list any ntfs partitions present. From there you can grep, awk, or check exit status to see if one is present.

If you don't have a working solution, hopefully this may help.

Thanks,
Tom
