This question already has an answer here:

I installed Ubuntu in my PC, but still I can run it with my USB (Try Ubuntu without installing) and I am unable to run Ubuntu without my USB drive inserted. And I find Windows instead of Ubuntu as one of the options in the Windows boot menu.

IMG:

If I run that option I get Windows 10.
