Help please: Could boot to Chameleon, but boot flags didn't help to get to installation!

Recommended Posts

Hey all!

First of all I have to apologize for my language mistakes, I am from Germany.

These are my Computer Specs:

- Intel Core i5 4460
- Geforce MSI GTX 970
- Asus Z87-C
- 12 GB DDR3 Ram (2 slots with 1600 MHz, 1 slot with 1333MHz)
- Samsung EVO 850, 500 GB SSD
- Seagate SSHD 2 TB

My Problem:

I managed to Boot into Chameleon Bootloader first.
Because I've read through some Guides here to get to installation with my Graphics Card (Geforce GTX 970 from MSI) I used these Boot Flags:

-v kext-dev-mode=1 nv_disable=1 GraphicsEnabler=No

After booting with these Bootflags installation started, and I could partition my SSD as I wanted to,
but while installing it suddently aborted, and there was an error.

Now everytime I want to try it again with the same boot flags, i can't even get to installation. It says (as attachment): "Debugger not configured. hanging"

I really want to get Yosemite running. I also included my BIOS Settings in the Attachments.

Please help me out! :D

Thank you!
