I have a RPI Zero Image on the micro sd card that runs fine on the RPI Zero. When I take that micro sd card and save that image from micro sd to local Windows drive. I then Write the image to a new micro sd card, it will not boot up on the RPI Zero.
If I use the Balena Clone tool, from source to new card, it boots up fine on the RPI Zero.
How can I save to back up a working image on my local Windows drive to be able to later Write to a new card that will boot on the RPI Zero?
How are you saving the image from the SD to local disk? I’d guess that the boot configuration of the SD is getting lost in whatever process you’re using.
Etcher doesn’t make images of SD cards; for that something like Win32 Disk Imager might work. Of course, the best would be to save the original image file you used to flash the SD card if available. Is this SD card using balenaOS or something else?
