I get the following errors when i put the installation disk in and try to boot ( I can't do -v without the disk because it doesn't give me that option it goes strait into the mac boot screen and freezes after 2 mins)

Firewire unable to determine security mode

Kextd [47} can't add repository

Disk arbitiond unable to mount

Sorry I am a noob and i don't know what this means.

Thanks for your reply
