do you have to dual boot?
 

ok so i was thinking of put snow leopard on a external hard drive so on my main computer is windows 7.
i was just going to ask do you have to have a dual booter on my main computer to run
snow leopard on the external hard drive or can i just install a dual booter on my external hard drive?

thanks in advance :)

Nope
 

No you don't have to do it at all.

When you boot just boot from the extrnal hdd. ig you want you could install chameleon and whenever you boot from the external hdd you could select to boot into win 7
