Having trouble dual booting Parrot Security OS with windows 8.1 Pro

[ROHAN-SNAKE]

First of all Sorry for my bad English. So my laptop is ASUS X75V Notebook Series. Windows 8.1 Pro is Installed. I wanted to install Parrot Security OS on it. I already Shrink a Volume for it. I've also created a bootable usb using Universal USB Installer. I've seen some post on how to install it and done same. I had to disable fastboot and secure boot and I selected primary boot to UEFI USB...

Everything I did was correct but when I was installing it.. I've press Esc to select boot option then select USB and pressed enter.

But nothing happens, it loads to windows 8.1 where I have to sign in. It is not booting in the parrot os installation.

What is wrong with it ?

Never Mind. I had to enable CSM in BIOS then it worked.
