Unfortunately, I don't have an 8 GB Thumbdrive. I have 2 X 4 GB though. I heard that you can use a partition, but I don't know how to do that exactly.
For the tutorial, I didn't even achieve the installation of Mac point. I want to install Lion, not Snow Leopard, Unfortunately, it's critical
EDIT: I got a new 8 GB Thumbdrive. What to do now? :/
