I installed NOOBS in my sd card and used Raspibian for a while. Recently I decided to change, so I opened my sd card and copied all the files to another computer (made a "backup"). I formatted my sd card and copied all the files back to the sd. However, on the boot, I receive the message "waiting for sd card (setting partition)" and no progress is made (I waited a few hours).
I beleive the sd does not have the correct partitions. But I found nothing on the subject that doesn't involve formatting and starting from 0.
Is there a way I can partition the sd and use it or restore the files from my old raspibian and update in a new one?
