If it is, the problem you are experiencing may be caused by incompatibility between the media and the CD-ROM drive. The solution is to 1) verify that the image you have downloaded is good by checking the md5 hash, 2) burn a new CD using a verified ISO image, and 3) burn slowly, i.e. < 8x. Another possibility is to use a different vendor of CD-RWs.
