Okay, so I'm installing Snow Leopard, Hackintosh, on my Dell Inspiron 1545,

Specs;
Processor 2.1 GHz Intel Core 2 Duo T4300
Memory 3GB, 800MHz DDR2
Hard drive 250GB 5,400rpm
Chipset Mobile Intel PM45 Express
Graphics Intel Graphics Media Accelerator X4500HD
Operating system Windows 7

Anyway, I've been installing Snow Leopard using this tutorial;
Install Snow Leopard on Your Hackintosh PC, No Hacking Required - Hackintosh - Lifehacker

When the boot from USB device begins, the apple logo appears, and the circle spins; then I get a "caution" sign, kind of like the "no smoking" ones, and so I rebooted and did a Boot Verbose, and these are the screenshots of the error I am getting.

How do I fix it?

It's says something along the lines of not being able to "enumerate a USB device"

which I'm assuming is my USB which is installing it?
how do I fix this?

Cheers.

bump! help!

You *could* try the flag

PHP Code:

rd=disk1s1 


Where disk1s1 equals the usb drive....

Hey if you are still having this problem it might be because of the fact that it is not recognizing your root device. To fix that problem go into your bios and in one of the options for your hard drives will be sata mode. Change the mode to ahci. Hope this helps!
