I have tried both Zephyroth dists and both of them start from dvd but when the Apple Logo appears the background goes grey and a windows appears that writes that I should restart the pc in various languages. What is wrong? I burn the ISO on a DVD+RW, is this wrong or my specs are not compatible?

AMD Athlon64 3200+
MSI NEO Platinum M/B
3x512Mb DDR Kingston RAM
3xWD SATA 200Gb
Sapphire x1650 256Mb
IDE NEC DVD RW

Please help
