Check the site where you download the iso. Look for the md5sum. When you have downloaded the iso, run md5sum on the downloaded iso, and compare it to the md5sum at the website you downloaded from.

After burning to disk, run md5sum on the disk. It it matches, your burned iso is also good.

Welcome to Linux Questions.

When you download an ISO image it's best to check the hash of the file before burning it to cd. The most common form is MD5.

On a Linux system you would do;

md5sum image_name.iso
On Windows you'll need to download an additional program to do this. Here's an example of one, but I haven't used it so can't comment on it.

This will generate a long string of characters. You then need to compare this with the expected hash value. Most distributions list the hash values for their CDs. For example, if you were trying to download an Ubuntu CD you would compare the result to the corresponding image name on this page;

If the two strings match you know your image is good.

Of course this doesn't account for problems with your CD writer or the media being used.
