iATKOS v7: grey apple then reboot

[madmonk]

Hi I just got a new machine setup and had partitioned the main HD into two parts to dual boot Win7 and then I was wanting to put 10.5.7 on the other partition. The other partition is already partitioned as FAT32.

I got the iATKOS v7 and tried to boot from it but all it does it it goes thru the darwin text prompt and then blinks the grey apple for a second then reboots.

My system details:

ASUS 6T6 motherboard
intel i7 920
NVIDIA 9800GT
SATA2.0

Any help would be appreciated. Thank you.
