Sorry I double posted, I see its more suitable in this section.

My laptop is a Lenovo G410 (4 years old)

Spec:
Intel Pentium Dual Core T2370 1.73GHz (not support VM)
Mobile Intel 965 Express Chipset family
Hard drive : 160GB (5400rpm)
3GB Ram

I want to know is there a way to install OSX Lion or just make a Boot USB for it?

I don't have any mac computer.
