Dell Inspiron 15R 3rd Gen - Ivy Bridge

[broomstick1300]

I have a Dell Inspiron 15R 3rd Gen that I've been trying to get Mountain Lion on, but every time I try I end up with the "Still Waiting For Root Device" error, I have AHCI in BIOS for SATA, but recently found out that the USB 3.0 ports may be causing it, it only has USB 3.0 so I don't know what to do to fix this issue. The system is Ivy Bridge, but I used the newest version of Unibeast to make the installer, but still no luck. Any help would be greatly appreciated

Specs:
Core i5-3210
Intel HD 4000 Graphics
6GB 1600Mhz RAM
500 GB SATA HDD

Try replacing these kexts on the USB Installer:
PXHCD.kext - Downloads - OSx86.net

broomstick1300: Please do report back!

iPerry4: Sorry, I don't really understand, why would you use Bridge Helper on Mountain Lion? 7 series are natively supported in ML.

Which directory do replace these in E/E or S/L/E ?

 

[silverkid]

That's normal, just ignore that error for now. It doesn't prevent you from booting, does it?

S/L/E

E/E is not really used anymore for kexts in Lion and up.

only thing i had to do was delete the bluetooth kexts from the install as it kept getting hungup on them

its weird i have a "compatible" system but its being a pain
Nvidia 630m and i7 3610QM
i keep getting unknown cpu which bugs up the powermanagement
and i dont have full graphics, stuck at 1024x786
