Now lets see

HOW TO SOLVE “STILL WAITING FOR ROOT DEVICE ERROR” AFTER INSTALLATION:

METHOD 1 AS SAID BY iCLARIFIED.COM:
follow the steps below so that you will be able to solve the still waiting for root device error after installation.

1.boot your pc using leoV3 dvd as if you are installing mac osx again.
2.now select the terminal from the installers utility menu.
3.copy the ATA kexts from the install dvd to your pc hard drive.for performing this action you have to enter the code as below

cp -pr /Volumes/Leo4allv3/System/Library/Extensions/*ATA* /Volumes/MacHD/System/Library/Extensions/.

NOTE*: Replace Leo4allv3 with the name of your install dvd and replace MacHD with the name of your hard drive volume.

4. Now we need to set the permissions for those kexts we copied

chown -R root:wheel /Volumes/MacHD/System/Library/Extensions/*ATA*
chmod -R 755 /Volumes/MacHD/System/Library/Extensions/*ATA*

NOTE*: Replace MacHD with the name of your hard drive volume.

5. To remove the kextcache execute the following:

rm -rf /Volumes/MacHD/System/Library/Extensions.*

Note* Replace MacHD with the name of your drive volume.

You may now restart your computer. I would suggest pressing F8 while booting and then entering -f as a boot option to force reloading of the kexts.

GUIDE 2:
THIS IS FROM APPLE2PC.BLOGSPOT.COM
If you know the number of your Hard Drive then at the Darwin prompt (after boot press F8) write: rd=DiskX where X is the number of your OSX hard drive.
For instance if your hard drive is 0 (zero is the first hard drive) then write:
rd=disko
if you do not know your hard drive then there is a try and error method of trying all the disk possibilities on your computer starting with: rd=disk0 then rd=disk1 then rd=disk2 then rd=disk3 etc. another good option is to disconnect other HD and leave the OSX HD as first and write disk0.
How to set the RD for every boot :
once you succeed and don’t want to write the rd parameter every boot, then write it in your boot plist file.this is a file that configure the system boot parameters. The file can be found at:/Library/Preferences/SystemConfiguration
The file name is: com.apple.Boot.plist and you edit it as root and change the Kernel Flags value and add to it the rd parameter like this:

1. Open terminal
2. Write: sudo -s and press enter
3. Enter your password when asked and press enter
4. Write: vi /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and press enter
5. In the vi editor use the arrow keys on the keyboard and navigate the cursor to the tag: after the <key>Kernel Flags< /key > line.
6. The string tag might be empty or not, if it is not empty then add space and then write: rd=diskX where X is your hard drive number.
7. Press keyboard button Esc (in order to exit insert mode)
8. Write: :wq and press enter (notice the : sign)
9. Then reboot and thats it
