Stuck at Apple boot Logo

I have a HP laptop with

Specs:

Intel i5-5200 CPU @2.20 GHz (4 CPUs)

4 GB RAM

Nvidia Ge Force 820M 2 GB Graphics Card

1 TB HDD

When I am installing Mavericks by Niresh it stuck at Apple boot logo.

I  have tried -v it stuck at "Read HFS+ file: [hd(0,1)/System/Library/Extensions.mkext] 4096 bytes".

Please Help !!

Try bootflag xpcm-free -f

if that does not work, you can try this dirty workaround:

2 years ago I was installing mavericks on my amd fx-8120 system and the installer hung at the exact same line. I did not manage to get past it so instead I just deleted Extensions.mkext and Extensions.kextcache from the installer.
