Yes you will have 2 OS, you just won't be able to boot into W8.

W8 is currently configured to work with your laptop hardware, it's not smart enough (unbelievable right in 2015) to notice, "oh I am in a new house now, I will reconfigure myself to work in the new box" - NOPE.

On top of that, Windows normally doesn't let you boot from a removable. I say normally because experienced folks have found way around it, but that will be up to you to Google.
