Q:

How to Boot from CD

I want to Boot Ubuntu from a CD. I have installed the ISO file on a CD. I have changed looked at my Boot priority list in my BIOS settings and I don't think my CD is there because I called it Ubuntu. What is in my Boot priority list is:

SANTA CD: SlimtypeDVD A DS8A9SH
SANTA HDD: ST500LM012 HN-M500MBB
USB CD:
USB FDD:
HDD:
NETWORK:

I have disabled Fast BIOS Mode and enabled USB wakeup but my CD still doesn't show in the Boot priority.
I have a Samsung notebook with windows 7 currently installed on it. I would like to have a dual boot. Can anyone help? If there are any more details that you need please tell me.

A:

We established that the issue was the user just wrote the .ISO file as a single file to the CD/DVD and did not burn the image.  This is why the answer is written this way.

An .ISO file is a file that contains a copy of the image of a disk.  To make an ISO work on USB, you have to burn the ISO to a CD drive.
If you did not burn the ISO, then you have a bad disk, and wasted a CD.
Read this page to know how to correctly burn the ISO to a CD/DVD.
