OK, I have an Asus Zenbook Prime UX31A-DH71 which came with Windows 8 preinstalled. I'm looking to upgrade to Windows 8.1 but need some tips or suggestions.

Now I've never installed an OS on a laptop before and imagine there are some slight difference between installing on a laptop and home built desktop?

What I really want to do is keep or reinstall the software that allows to laptop to instantly boot/load. I also don't plan on deleting the hidden partition containing the restore image.

Keeping those in mind any tips, help or suggestions would be greatly appreciated.

Need to add I do have a Win 8.1 install disk, and a valid PID.
