I have a .daa image file which I need to burn and boot from. What (free) program can I use to do this? Will there be any problems burning/booting/reading this disc? I've just never heard of this type of file before, so I wanted to be sure.

That is a Poweriso file:

Not a free app I'm afraid, and I don't know if there are free apps that can handle that file.

Ok. But my computer should have no problems booting from the disc and reading it?

If it is supposed to be a bootable image, and its not corrupt or anything then yes you should be able to boot of it without problems.

Ok, thanks.
