Ok, sorry for the delay, I did figure out how to disable secure boot. My UEFI page has 2 places in which secure boot is designated, and it is a bit confusing, but I got it to work. Now, as to the patches, where I am starting, I am so far getting different results than Harri. The first thing to note is that patch number 12 fails for me. I will post the results here when I finish testing them all.
