4GB SD Card image to 16GB SD Card - only 4GB storage shown

[jojo_angelov]

Hi everyone. So I created my Raspberry pi setup and everything was great. I originally used a 4gb card and I made an image out of it. I then decided to write it to a 16gb sdcard since I needed some more space, but now I notice that the pi only recognizes the original 4gb space, and so the rest 12gb are pretty much not recognized anymore.
Is there anything I can do to expand the size of the image to utilize the 16gb sdcard?
It seems unnecessarily complicated to have to setup a whole new card if you want to expand the size.

Thanks guys!

If it's a non-noobs setup from a foundation image then you should be able to use the expand rootfs option is raspi-config.

If you have a linux box available gparted should be able to resize the partitions.

Open terminal, type sudo raspi-config select expand roots

That does not work for a NOOBS card.

For a NOOBS card you need to boot an alternative copy of Raspbian, mount your 16GB card in a USB SDCard reader and use parted or gparted to resize the extended partition and resize the ext4 partitions in that extended partition.
