Sharing my experiences across Linux usb booting in general, not merely the laptop. Booting an OS from USB is doable, but not recommended on any computer in my personal experience (edit) outside of live booting a distro. I’ve done it across a spectrum of operating systems and computers. It’s flakey and while doable, is not recommended by me based on those experiences.
So hopefully that clears that up. That’s my recommendation. 
Moving forward, in your case, you will want to reach out to support for an expansion card replacement.
You definitely will want to have the card replaced.
