I have an iMac from 2010 and the Snow Leopard DVD and I am trying to do a clean install of Snow Leopard on it. Then, if I use the Install Snow Leopard option from the DVD, when it restarts it hangs on the apple icon, but if I restart the Mac nothing happened to my HDD.
I also tried using booting the DVD by holding 'Option' when I restart it, and after I choose to boot from the DVD, it hangs on the apple icon and I can hear that the DVD stop spinning.
I boot it on safe mode and use the Apple Hardware Diagnose Tool and no issues have been shown. I will appreciate if anyone have an idea of how I can perform this clean install. Thanks!
