I tried to mount my Ubuntu 13.04 64-bit image using the following command :

sudo mount -o rw,loop /home/varun/Downloads/ubuntu-13.04-desktop-amd64.iso /media/cdimage

But I gets the following warning :

mount: warning: /media/cdimage seems to be mounted read-only.   

Help me to eliminate the warning.

ISO files are always mounted as read only. So copy files from the mounted ISO to another folder and then make changes you want. You can then use mkisofs to generate a new ISO from the modified folder.

  • I copied the file and entered the path using this command to jigdo :jigdo [/media/cdimage]: /home/varun/Downloads/Ubuntu . But it shows "Enter the no.of images". What should I enter ?

As explained in other answers, ISO images apparently always get mounted as read-only.

If you want to make changes to your *.iso image, use a GUI such as ISO Master or Furius ISO Mount. See How to mount an ISO file? for details.

  • Is there anything like that which still functions in 2023?
