Hi!

I hope i have understand your problem right. You cant get to the installation. Do you get the Apple-Screen with its loading symbol?
I had the problem, that after 10 seconds of the loading screen my machine had to restart. So it wasn't possible to get to the installation.

Did you tried to pull out all harddiscs (ide + s-ata), so that the only thing left is the cd/dvd-device?
That solved my problem of rebooting. So I changed some master and slave things. I also had to put my
DVD device on the same cable as my IDE harddisc. Right after the installation i was able to set up the
old cable structure.

Good luck, bye
