Your dd line is very suspect. Why are you using a block size of 32k? The sector size of most CD-ROMs is 2k. I've certainly encountered my fair share of CD-ROMS that were an odd multiple of 2k. dd will silently truncate the ISO if the size is not a multiple of 32k.

And I'm sure CD is bootable. (Not pirated, original.) OTOH, if we'd assume the ISO image is corrupted for some unknown reason, why "-cdrom /dev/scd0" didn't work? Regards.
