This question is an exact duplicate of:

I'm trying to install Debian from a DVD. The DVD is a dual layer disc which can multi boot into 32 or 64 bit Debian or Kali Linux. I created the iso for this using a program called XBoot. The disc loads fine and I can select the distro I want, but for all of them I get "Incorrect CD-ROM detected" error when installing.

From Google searches I can only find people with this issue when installing from a USB. Is it just not possible to install Linux from one of these multi boot DVD's?
