[AdwiL]

Hello!

I've installed iAtkos 7 on my Acer Extensa 5630 but after reboot everything is stuck on Apple logo.

Specs:
Processor: Core 2 Duo T5800 (10x200)
Chipset: Intel PM45
RAM: 2x 2GB Kingstone 800MHz
Graphics: ATI Mobility Radeon HD 3450
Sound card: Realtek ALC268
HDD: Fujitsu 60GB (second disk for Mac OS)
WIFI: Intel WiFi Link 5100 AGN

What do I have to do?

PS
I'm really new in this stuff so please be patient
