Hi again,
finally I have time to try the installation of Mac OS 10.8 again.
I still have some trouble to boot the system.
Here is what I have done so far:
I created the bootable USB with myhack 3.3.1
And I added the DSDT like it was mentioned in this guide.
"Once MyHack has created the USB, download the DSDT I have attached and move it to /Extra/ on the USB. This will enable you launch the USB with no problems."
EDIT: I also downloaded the latest EDP pack for 10.8, here in the forum.
Afterwards, I started my computer again, chose the USB, deleted the partition (mac os journaled) and started the installation.
At the end of the installation, I chose "use generic ones" and clicked every time on "yes".
After the restart, I pressed ESC for the boot menu and I chose the USB again. Then, I chose the Partion with Mac and pressed ENTER. As this did not work, I did this again... but this time i said "-v" and pressed ENTER.
A lot of things loaded until it said "NTFS volume name version 3.1."
I tried to do this booting process with "-x" again and I was able to complete the installation. I am also able to boot it now with "-x".
BUT on the starting screen, where I enter my password, it says in the right top corner in red color that it is a secure system start (or something like that, I use German language).
When I enter the system, I get directly the following message:
and I am not able to run myhack to install Chameleon.
Therefore, i tried booted the USB Stick again to get to the installation process where I clicked on Utilities and used myhack to run myfix AND to install Chameleon but nothing worked.
I also tried it with VT-d disabled and enabled
Just in case that this helps.... this is the bootlist which i copied into the folder "extra" (latest EDP pack for 10.8):

I really don't know what to do now....hope that someone can help me.
Thank you
