freezes on splash after install

I've completely installed iDeneb v1.5 and upon restarting i get chameleon loader. when i select mac os x it goes to to the grey splash screen. the little grey loading wheel under the apple goes round and round and then all of a sudden a small grey "no" symbol (circle with a line through it) appears in the center. at that point i assumed it was no longer loading and i rebooted

In verbose mode it stops at:
"
Extension "com.apple.driver.iTunesPhoneDriver" has no explicit kernel dependency; using version 6.0.
ERROR: firewire unable to determine security-mode; defaulting to full-secure
Still waiting for root device

my specs:
Asus P5K-V motherboard
2gb OCZ ram
Intel Core 2 Duo E6750
Western Digital Sata HDD (only for OS X. Vista is on a seperate HDD)
ATI HD2600 Video Card
Sata DVD drive

I looked everywhere for a solution and couldn't find one so THANK YOU FOR ANY HELP YOU CAN OFFER!:)
