When you burnt the iso image did you make sure to check the md5 sums and did you write it at 4X? If you didn't do these you can run into some big problems.

Did you simply burn the ISO file to the disk or did you "create" the disk using the ISO file? You also do not need to "make" the disc bootable. It is bootable if made properly from the image.
