Hi all, i wanted to test out the SnowLeopard, but as i know, its not ready for use as main os use. I burned the snowleopard onto a dvd, installed it "live" in the os, and works. But when i take the installation disc's that i got whit my Mb Air in the cd tray (external superdrive) i get one option, and thats to hit restart and boot up from cd to install, but when it boots up again and the chime and gray apple logo screen shows up, the cd is spinning up but after 1min its restarting again. This it goes forever. What should i do? I have tried different install disc's, and the computer is a MacBookAir. And Apple Mac OS X 10.6 Snow Leopard (Build 10A380) are installed.... Thanks!!
