i installed iAtkos v7 with the openhaltrestart kext chosen in the customize menu.
when i restart my hp8510 hangs at siver mac screen. when using boot options -v -f i can see that it stops after openhaltrestart.

Somehow im a not able to boot from dvd anymore.
Is there a way to remove the openhaltrestart in the boot option - like the -x or something ?

thanks in advance
