Have never had a problem doing this. CDs and DVDs I have burned from iso files have always been bootable. I would say check you bios if you were not getting that bootable disc message. So I think the place to look at is setting up writing the disk or USB stick. I did have one friend who had this problem. When I checked his boot disk it had one file on it, with the extension of iso. But check you bios just to be sure.
