ML crashes before graphical interface, tried about everythin


Recommended Posts

I am desperate. I’ve tried two motherboards and two processors. I can never get to the graphical install interface on ML. I have gotten to the point of “waiting on root device†but I’m not able to get there now. Whatever I try: multiboot (chameleon, stolen and rebranded), crackwalk or myhack, each reboots when it gets to that point of loading the graphical interface. Even though I use the –F switch, it does the same thing and I can never see the error. It doesn’t “halt†where I can read the messages.

First motherboard & chip: z68ap-d3 (2.0), G630 Sandy Bridge 2.7 GHz, asus 210 Ge Force 512 MG (video). Second motherboard: B75M-D3P, i3 2120 3.3 GHz (video on board). Same results.

I have used about every switch I can find online (DSDT=no, GraphicsEnabler=no; -v, -x cpus=1 busratio=18; -v npci=0x2000 cpus=1 GraphicsEnabler=No; debug=8 ahcidisk=1; HPET, 64 bit, ACHI). I even flashed the z68ap motherboard. I have a working rig, using Snow Leopard that is “incompatible with ML.†I built that rig from scratch and had no problems. I have changed stuff in the BIOS trying to install ML until I’m almost blind. I have re-set to default settings and tried again.

I am willing to try anything that anyone suggests. I also have a MacBook Pro I can use to make stuff. Someone p l e a s e give me something different to try or do. I can do things in terminal in single user mode if someone will give me step-by-step directions.

Please help.

Please post in a well organized mater so that people can follow what your specs are and what you have done. Second I can tell you have no understanding in regards to what the boot flags do so please review the following before continuing:




There is a non fixable with this system:



Intel I3 2120

HD2000 (Unsupported So Do Not Bother)


Looking at:


Gigabyte z68ap-d3

Intel Pentium G630

Asus Nvidia 210


Boot with myHack with the following flags:


-v GraphicsEnabler=No


Post a pic were it hangs showing the full screen. Also make sure you are not connected to a USB 3.0 port and are using a USB 2.0 port on the back of the system.

I have the code; it is below if someone can help me figure out what to do next:

Again you are not following what I had asked you to do. You booted with:


–x –f –v npci=0x3000 GraphicsEnabler=No


Please boot as instructed and you have NO IDEA what you are doing in regards to boot flags so please do not experiment. With what you booted with it will never work. If you want help DO AS TOLD.

This motherboard doesn't have built-in graphics. I'm using the Asus 210 Geforce.

There is an onboard vga setting but there is no "off" for it; just Enable if no EXT PEG, always enable and Auto. On anything but auto, it reboots rather than showing what stops the process. If there something I need to do in Myhack to change that?

Under Advance BIOS Features:


Onboard VGA

Enables or disables the onboard graphics function. Auto

Allows you to set up a dual-display configuration in Windows 7 operating system. (Default) Enable If No Ext PEG

Activates the onboard graphics only when no PCI Express graphics card is installed. Always Enable

Always activates the onboard graphics, whether or not a PCI Express graphics card is installed. If you wish to set up a dual-display configuration, set this item to Always Enable.


You just needed to take it slower and look at all the menus.
