[Epke]

Hi,

Ive installed Leopard succesfully I was running zephyroth 10.5.1 amd succesfully, but now I installed his latest version 10.5.2. And now
I get after install while booting the error: "Error loading operating system"

How do I fix this?

My specs:
AMD Athlon X2 5000+
2048MB ram
Nforce 5 Motherboard
Nvidia 8600GTS

Nevermind fixed it with a new install, but now when I get the loading screen after that my screen begin to flicker, so I think wrong nvidia kexts?

Best to get booted into Leopard prior to installing any extra kext's to minimize errors.
