Ubuntu is on the desktop downstairs. The laptop has Win10 only on it, which was Win8 until Win10 installed itself on the sly... Anyway, the plan, when I decide to take the time, will be to dismantle the computer and take the drive out (it's a Dell, and "protects" the hard drive) and move it to the Ubuntu machine for re-formatting. My main concern is that even with "fixing" the current Win10 install with a full re-install, is that it will be a brick again in just a few short weeks when MS decides to do further uncontrolled, "live" experiments... I do have another MS seat license for Win7 available, and might go that route. I would do Ubuntu on it, if I didn't have certain "requirements" that Ubuntu can't do (proprietary stuff)...
