There's multiple ways, but these two are probably the easiest.
Remove the ME drive completely.
Set up NT with the multiboot option.
Add the ME drive.
OR...get a multiboot loader. I recommend
http://www.xosl.com as (probably) the easiest to get and setup.
With xosl, you don't have to remove the ME drive. Just install xosl on your ME drive, and then let it specify which drive to boot from.
