WAIT! DON'T UPDATE TO WINDOWS 8.1 JUST YET.

I had installed Windows 8.1 and boy do I regret it. I have to reinstall Windows 8. Here is my problem...

"Secure Boot isn't configured correctly" watermark appeared on the my desktop.

Tried to enable Secure Boot in BIOS and that did not work. Plus I had some driver issues with Windows 8.1 which I feel it is just not worth the trouble to install.

It was written online that Windows 8.1 launch was plagued by some installation issues, you can read all about it here.

So I have given you my warning. Take heed.
