I am following the tutorial posted at http://www.hackint0sh.org/f217/188641-6.htm

I am currently running windows 7 (obviously lol) and I created a new partition to install Snow Leopard on.

Since the m11x does not have a cd drive, I've had to use my external hard drive to try to install it. I created a new partition on the external hdd, made it the primary drive, and put the iAtkos iso and extracted files on that new partition.

When I boot up I press f12 to go to the boot menu (usb emulation enabled) and select "usb storage device" or something similar to that. A new screen comes up and says:

Check cable connection!
PXE-M0F: Exiting Intel PXE ROM
Invalid partition table

I have tried connecting it to different usb ports, but no luck.

Would the only possible way to do this would be to format my whole external hard drive?? Or is the error message related to something else?
