Could you describe how to do the easy method without using Windows? I tried 7za and that extracted an img file but using dd to put that on /dev/sdx leads to there being no partition table on the sd card. What do all these "may contain malware" windows utilies actually do ?

In the not-so-easy method, what leads to the blob file being used? Should I run update grub or something?

So far i have a completely black screen.
