Dell Mini 10v Hard drive not being picked up

Ok first a warning - complete and utter noob. So I found my idiot proof guide-

I'm following this guide exactly How To: Hackintosh a Dell Mini 10v Into the Ultimate Snow Leopard Netbook - Dell mini 10v hackintosh - Gizmodo (giz modo.com/5389166/how-to-hackintosh-a-dell-mini-10v-into-the-ultimate-snow-leopard-netbook)
Bought a brand new dell mini 10v, copy of snow leopard, usb. Did everything it says. I get to the spinning apple screen, language choice, then it asks me where I want to install leopard. I'm told to format my hard drive - yet only the usb drive is showing up in disk utility.

Surely I can't have an unsupported hard drive, seeing as dell mini 10v is 'the' hackintosh netbook at the moment...? Am I just being thick?

If someone could help me out I'd very much appreciate it! I have an external cd drive but no external hard drive and no money to buy one, so if my hard drive is at fault I'm a tiny bit pooped.
