Install OSX on Eeepc 1201HA, Howto ? Failures sometimes

Hello :)
After some times, I've successed to install OSX on my Hard Drive with an external HD USB, after recreated a GUID table partition.

But after reboot, when chameleon runs I've a: "Mach_kernel not found" when I decided to launch OSX.
Have you got any idea ?

I've successed to install OSX on a HFS+ partition, but after the reboot I can't boot on OSX because I've a "mach_kernel not found".
Could you have a solution ?
As before the installation, I boot with chameleon :)
Any idea ?
