use USB-HDD as internal HDD?

I have an USB HDD and can i make it like the computer sees it as an internal one so i can install multiple OS's on it?

Take the drive out of the case and install it internally.
There are ways to install an OS on an external USB drive, but it is not easy, and will be dirt slow if you ever get it running.

Hey Royvds. If I were you, I'd follow @USAFRet's advice. Other than that, I just wanted to add that you should backup any important data which you might have on that drive before you take it out of the enclosure, especially if there's a hardware encryption if you can't afford to lose your files. Also note that taking the drive out of the enclosure would probably void the its warranty.

Hope that helps.
