Howto make iso image

Filed under: GNU/Linux, Howto — shirwa @ 12:07 am

To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it.

# umount /dev/cdrom

Create iso image with dd comman:

# dd if=/dev/cdrom of=/tmp/cdimage.iso

  • if = input file (/dev/cdrom).
  • of = output file (cdimage.iso)

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command. mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.
