How to Fix Still Waiting for Root Device in Hackintosh

You may have faced this error while Installing Mac OS X or After a Successful Installation may be in Hackintosh (OSX86) or real Macs
In this post I’m going to explain this problem and suggest a solution with using my personal experience.

What does “Still waiting for root device” means ?
Its very simple, it means that the source from which you’re booting is not detected properly in other way
it can be explained as the operating system was not able to locate a driver/kext for your Hard disk/DvD Drive/USB

The OS X Comes with the latest drivers that supports SATA out of the box
but you may face this issue

If you’re using an old motherboard
if you have a PATA ( Parallel ATA ) Port
If you have a Gigabyte Motherboard.
If you’re using a USB-Hard disk/ USB DvD Rom/ PenDrive to Boot

This problem occurs before/after the installation but it depends on the Boot Media
In This Article i will explain them by dividing the problem types in to three cases

Case:- 1

You May be trying to Install Mac OS X Using a Bootable USB .

This occurs when Your USB Port is not recognized by Mac OS X & In some LGA 1156 motherboards they need to use some additional kexts to Make USB Work Properly.

How Can You Fix It? (Solutions)

Try to boot with the kernel flag USBBusFix=Yes this usually triggers All The USB Ports & Fix all usb related issues
LGA 1156 motherboard Users Install Zenith432’s GenericUSBXHCI.kext into the Bootable USB ( /Extra/Extensions ) Using Kext Wizard / Transmac (If you’re using windows)
Try to Enable/Disable Legacy USB in Bios

Case:- 2

Try to Set SATA as AHCI on Bios
Try to Change SATA Ports
Connect DvD to Primary SATA/PATA Port

If these doesn’t help stop trying its unworthy to try in this case

Case:- 3
