Which "dd" command do i use to dd a downloaded OS over to a usb?
by olddogg from LinuxQuestions.org on (#5R4Z0)
debian buster 10 orangepi
When I have a newly downloaded OS copied to a microsd (microsd attached to my main OS similar to a usb on the side of a laptop), then I use the basic dd command to copy it over to another microsd: "sudo dd if=/dev/sdx bs=100M of=/dev/sdy". But this can only be used when "copying" over the entire microsd to another microsd of the same size, etc.
But for my newly downloaded OS that I want to "dd" over - it is located in the downloads folder of the main OS that I am using right now; in other words I downloaded it to my "hdd".
The newly downloaded OS is going to get dd'd over to the entire microsd (sdy). But I know I can not use the command I listed above since that copies everything over to sdy.
I just need to copy over the newly downloaded OS on my hdd over to the microsd OFF of my hdd. I know there is a dd command for this - don't remember it.
Thanks.
