Windows 7: Hiding Autoplay dialog from Autorun.inf

How can I hide the Autoplay dialog from the autorun.inf file?
I have a USB with two partitions: A bootable linux partition (recognized as a fake CD drive by windows) and the normal "Removable disk" partition, where I can store my files.

When I plug in my USB into any computer, I get two autoplay dialogs, which is very annoying. Is there any line I can put in Autorun.inf to disable the Autoplay dialog on the CD partition?



I tried

but it didn't work.

This website lists all autorun commands:Autorun.inf Entries

I'm sure the malware authors would love it if such an option existed...

I don't mean hide the autoplay but run the file anyway.
I mean HIDE the autoplay AND don't run ANYTHING - because I'm sick of plugging my usb and getting two autoplay dialogs.

I wish to do this from Autorun.inf because I frequently plug in the USB into many different windows 7 computers, especially at work, and I cannot modify the registry settings of these computers and so on. Recently it has really got on my nerves to the point that I think I'm going to buy a new USB that doesn't have "virtual CD" functionality.

Any help please?
