I had been toying with the idea of trying Linux for a long time but never got ambitious enough to learn it. A week ago Microsoft decided it was a good business decision to make me watch an advertisement every couple of games of solitaire. No thanks. Even though I got Win 10 for free upgrade from Win 7 this is not right. I downloaded the Ubuntu image and made a bootable flash drive. The instructions I found online all said dual boot was the selection to make but it wasn't there. If I was single I would have let it remove Win 10 and put Ubuntu on the computer. I checked online again and am seeing if chkdsk will fix the problem.
