Re: ubuntu Software Center wiped out system, can't boot.
I have USB 3 ports on my computer as well as USB 2 but I know with my PC the computer will not boot to USB 3 ports only 2. I don't own a system 76 computer though so yours may differ.
Ubuntu 10.04 is no longer supported and will not receive any updates so I recommend against that.
