HP ENVY m6-1225dx Notebook PC Mountain Lion 10.8// Help!

Recommended Posts

Hello ! 


Im trying to install OS X Mountain Lion 10.8, im using the last MyHack with and InstallESD.iso i downloaded this iso from the piratebay long ago, i succesfully got to install 10.8 on other Desktop PC's using MyHack and this ISO. but now im trying to install it on my HP ENVY m6-1225dx Notebook PC, but i always get stuck on Still Waiting For Root Device also i get error encountered while starting up the computer pausing 5 seconds




1. error encountered while starting up the computer pausing 5 seconds

2. still waiting for root device




My BIOS it's locked...there's nothing that i can do, just enable the legacy option to be able to boot from my USB drive which is the one that i've always have used for my installs.





Intel Core i5-3230M// 2.60GHz

8GB Ram 

Intel HD4000

750GB 5400RPM 


More Specs here: 



Kernel Flags i've have used: 


cpus=1 //to avoid the KP

UseKernelCache=No // to see if i was able to avoid Still Waiting for root device, no luck

USBBusFix=Yes //  No luck.

another one that goes by ForceEHT(something like that) /// no luck either


Help :S !
