I have two miners working well, how to upload the image?
I want to help.
Use win32 dis imager;
Choose as the directory where you want to produce the image and name it miner
.img (or sth. else, but keep the .img)
At the right of that choose the drive your sdcard ist (e.g./H)
Press the read button.
It will then read the sdcard and create an image.
This image would help many people on here if you upload it e.g. in your dropbox and share the link.
I would recommend compressing it in a zip-file.
Also, you will have your own backup, if one of your sdcards should fail.
