I hpe you got the .ISO file and then used a proper burner like IMGBURN(free) and then in its setting used "make bootable" or similar. I also use CDburnerXP(free) and again use the .ISO file gotten, burn it. Make the CD drive the 1st boot device and it should work. You can't copy files to a blank CD or anything like that, it just won't work. Try this again, using the s/w I suggested it should work.
