I'm trying to dual-boot Vista and Leopard. I made a 30 GB partition for Leopard. When I try to install Leopard using the iAtkos disc, I either get the Not Allowed sign, or in diagnostics get: Still waiting for root device. I'm using a different version for AMD processors, so thats not the problem. I tried all the solutions in that sticky that involve typing, but none worked.

Here are my specifications:
Model HP G60
System Board ID 303C
Processor AMD Sempron(tm) SI-42
BIOS version F.35
160 GB SATA HD
NVIDIA Graphics Card
Here are some pics:
The last line before "Still waiting for root device" is:
USBF: 8.392 AppleUSBOHCI[0x38148000]::CheckSleepCapability - OHCI controller will be unloaded across sleep
