You got it.
that Toshiba has always been a problem, touchpad never worked even when new and was a lone Windows 8.1 beast. I’d had the machine over a year, so warranty was dead and when I tried to burn an ISO for the first time, it failed - and it wasn’t the media.
The keyboard was dreadful, no matter how you configured it, you either got unwanted doble strike or the opposite no double letter when you actually wanted it,
When I bought a gaming Win10 in September, replacing the Win7,I realized I could dual boot it and thus this saga began, LOL.
After all the LTS upgrades since Dapper Drake, I figured one more would be no problem. D’oh!
