Hello,
 
I have a Samsung a NP370R5E-S02FR laptop (samsung serie 3) with the following specs :
- intel core i5 3210M
- AMD Radeon HD 8750
- SSD samsung 840
 
System infos :

I'm trying to install moutain lion, but i can't pass the boot step...
I have the message "Still waiting for root device"
 
My bios setup :
Execute Disable Bit : Enabled
AHCI mode control: Manual, set AHCI Mode = Enabled
Secure Boot: Disable, OS Mode Selection: CSM OS
 
I have tried some boot flag (-v, -x, -f)
Without -x, i have a kernel panic
I tried some combinaisons with PCIRootUID, npci 0x2000 0x3000, graphicsEnabler...
 
I tried delete extension in E/E, but always the same mesage "Still waiting for root device".
 
The same message is present with all sytems I tested : #####, myhack, iaktos...
 
I have an other hackintosh which works perfectly, but on my laptop I don't know what do...
 
I listen all ideas, thanks :)

Thanks to reply. I have add this kext in E/E.

 

No more "Still waiting", but block on "IOBluetoothHCIController start -- completed".

And before, 10 lines of "Refusing new kext comp...IOPCIFamily : A loaded with a different executable UUID is already present."

And when I replace IOPCIFamily.kext to yours kext in system/library/E, i return to the "still waiting" message.

hello

 

take a good read here

 

Intel HD 4000

 

to boot the installer try to remove appleintelhd*capri

 

and my idea is not to put the kext in E/E

 

that is not used anymore .. after lion mac os x use kernel cache.. so all kext in S/L/E

 

good hack

Hm. I tried only MBR, i'm going to try GUID.

 

My BIOS settings :

mini_787683IMG20130922170259.jpg

mini_257329IMG20130922170307.jpg

 

Boot with UEFI can change anything ?

 

thank you for help.

No change with GUID...

 

I don't know how I spent the step of "still waiting" to this : http://www.hostingpi...30922153144.jpg

This was when i have add your kext in E/E.

 

I try to do it again, but i have only "Still waiting..."

 

I think this is very random.

Okay, it's much better!

 

I boot only in safe mode but i can install mac os.

(And i have deleted all video kexts to avoid a black screen...).

 

I can boot on mountain lion installed, in safe mode only again...

(800x600, no touch pad, no sounds, no battery indicator...)

 

My screen without safe mode :

mini_990398IMG20130923223537.jpg

 

 

(And how can i add some flag option with clover ?)

 

Thank you!

Update.
 
After some tests, i can't boot without -x.
 
With all video kexts : black screen during boot, with or without "-x"
Without video kexts : screen freeze (see capture above), OK with "-x"
 
Without "-x", i'm flood by many "SMC ERROR" lines. It's important ?
 
With -x,
I boot in 800x600 with chameleon, and i boot in native resolution with clover (but graphics are laggy).
 
I have read many threads on hd4000, but no results.
 
I don't know what can i do.
Work to boot the installer without safe mode or work in post installation ?
