      @aussie-daredevil Then I suggest to use a Linux live distro like System Rescue CD - that you can run from your PC from an USB stick - to resize the partition (/dev/sda2). It has a graphical interface for gparted, the program used for partition resizing, and it's really easy to use.

      I think there are also Windows programs that can do that, without the need for a Live CD, but I personally didn't use any and can't remember the names.

        @mitu already tried gparted thru Linux live, didn't work, even tried a smaller partition size of 500gig with no luck. Here is a screenshot of the logs!PicsArt_06-05-02.12.17.jpg

          @aussie-daredevil This is because your /root partition UUID has changed - you need to modify the /boot/cmdline.txt accordingly - put the new UUID there. You'll also have to modify the /etc/fstab file and add the replace the existing UUID with the new one.

          You can find out the new UUID from the live cd by running blkid.

              @aussie-daredevil You have 2 partitions on the new disc. You'll need to mount both from the live cd and perform some modifications.

              • /dev/sda1 contains the /boot folder with the kernel and necessary config and firmware files. Open the cmdline.txt with an editor and replace the UUID=<XYZ> part with the UUID=<actual_uuid>, then save the file.
              • /dev/sda2 contains the / filesystem. Open the the /etc/fstab file (it's a text file) with the same editor and replace the 2nd line with PARTUUID=<XYZ> with PARTUUID=<actual_uuid>.

              The <actual_uuid> should be replaced with the UUID corresponding to /dev/sda2, which you can find out by running blkid from the command line - it should print the UUIDs of all partitions.

                  @aussie-daredevil You'll have to be more specific, I can't guess from monosyllabic responses what are your intentions.
                  If you feel it's too complicated, then I recommend you install from zero on the new disk, resize the large partition with gparted from a live CD and then copy over your configs/ROMs/artwork/what have you.

                    @mitu what I was asking can I use rasbian to edit files but I have found that I cannot edit sda2/etc/fstab.txt as it says I do not have permission.
                    Is there another windows program I can use to edit this? Or another way to do it on rasbian?

                      @mitu and thankyou so much for your help, I've never used Linux before and have only been tinkering with the pi the last 5 days. So I'm a big arse noob atm lol.

                        @aussie-daredevil Then I recommend starting from scratch with the new disc, make sure it works, then transfer your files to it from your old drive - ROMs/artwork/etc. See the 2nd backup method explained in the docs - https://retropie.org.uk/docs/Updating-RetroPie/#making-a-backup-option-2.
