How can I determine if a CD is marked as bootable?

I am trying to install Windows XP on a old laptop (Compaq Presario 700) with a stored verion of XP that I burned to an ISO.

The copy of XP is legitimate but it won't boot to it. I am able to boot to the Crap Recover CD that is basically just DOS, and to a copy of "Ultimate Boot CD v5" that I downloaded and created from the same computer and burner that the XP cd was made from.

Everything boots except for this XP CD. Is there a way to tell if it's bootable?

Solution 1:

Use a tool like UltraISO. It will indicate that the CD is bootable.

Solution 2:

It sounds like it's not bootable but you could use IsoBuster or one of many similar programs to check the ISO file or the actual disk.
