Lets start from the beginning:
1 Open a terminal in Zorin, then change to the directory that the Ubuntu 13.04 iso was downloaded to. For example:
Then check the md5sum of the iso image:
where xxx represents the exact name of the iso image you downloaded. The output should match the md5sum from the mirror site where you downloaded the Ubuntu 13.04 iso image from.
If that checks out, then how did you burn the iso image? Be sure to burn the CD as an iso image, and not as a data CD, and burn it at the slowest possible speed for best results.
Then if you put the CD with Ubuntu 13.04 into your CDROM drive and open it on your Zorin system it should contain many files and directories, and not just be one iso file on the CD.
To verify that the CD md5sum is correct, see this tutorial on how to properly check the md5sum of an iso image CD: http://twiki.org/cgi-bin/view/Wikile...msAfterBurning
The salient part of that tutorial is this command:
dd if=/dev/cdrom | head -c `stat --format=%s /ISO/Mandrake/MandrakeLinux-9.2beta1-CD1.i586.iso` | md5sum
Just replace /ISO/Mandrake/MandrakeLinux-9.2beta1-CD1.i586.iso
with the path to your Ubuntu 13.04 iso image. Also, since that tutorial is a bit old, I replace the /dev/cdrom
in the beginning of that command with /dev/sr0
, since that is how optical drives are named these days on Linux.
If all of this checks out, you should be able to boot from the CD just fine, as long as your BIOS is set correctly.
This may seem a bit complicated for a beginner, but once you have done it a few times it becomes just another routine that you do.
This is how I verify that my iso CDs are burned correctly.
Write back if you need more help.
