Mountain Lion Installation Failed

[alsaadie]

Hi,
I keep getting an error each time I'm doing fresh installation of the Mountain Lion, im getting the bellow error each time just at the end of the installation :
"The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."

I followed the bellow link literally, but i keep getting the same error
tonymacx86 - UniBeast 1.5: Install OS X Mountain Lion on Any Supported Intel-based PC

Although, i can start Mountain Lion from the the disk with the failed installation !!!

Here is my specs:

Gigabyte GA-P55A-UD3P
Intel i5 Quad core
8GB DDR3 RAM
1GB Nvidia 9800GT Video Card
Tried multiple disk drives


Any idea what might went wrong ?, and can i keep using mountain lion (although the installation had fail)

Regards
