Hi there

I have here a problem for more than a month now trying to search for some solutions,
so this what happens, I bought a laptop from a friend which is in a very good shape but the thing is it comes with the Phoenix OS which is I believe a Linux bases OS.
so what I did is trying to install a Win7 to this laptop using a USB drive, and yes laptop is able to boot up from the USB boot drive with Win7
and able to install it properly, so after installing the Win7 I tried to start the laptop and what i got is just a screen says "Starting Windows" and hangs. the only way to turn the laptop off is by pressing and hold the on and off button.
PLEASE HELP
