yeah that is partly why I'd recommend apple hardware or a virtual machine. I'm not sure that the hacker community has written support for the fx processors yet.
Still You may have better luck burning the osx image with the boot support to a DVD. Though it sounds like the thumbdrive is recognized, it's just some files are missing on it.
What image are you using on your thumbdrive?
Basically apple worote osx only to work on their hardware. It's up to volunteer hackers make the pieces that would make OSX work with each different hardware part. so each different chip on a mtherboard needs someone to write a small bit of a program for it to work.
The Intel motherboards have the most in-common with the apple machines and work best since osx runs native on intel hardware. The next easiest would be a VM, since the vm can be made to look like any hardware the creator wants they can choose hardware similar to what has already been written for support. Actual hardware support for amd is the most difficult. It shares the least in common with Apple hardware and needs the most hacker support.
Your best bet to make your new system work is to have a dual boot, this will let you do SOMETHING with the system as you are working to make it a hackintosh. This is a project that will take some real effort on your part to make happen. I just wasn't willing to personally put the time ine once I saw there was no easy way to make this happen ( I sent around 10-20 hours) trying to make an install work on my am3+ system.
