I know that Win 8.1 (Basic Pack) cannot be upgraded to Win 8.1 enterprise directly, by "add features to 8.1". I have the 8.1 enterprise image (ISO) and my very own product key.
Here is the problem:
My laptop is a Lenovo Manufactured. The win 8.1(x64 basic pack-single language pack) is pre-installed OEM-UEFI in it. Seems that the basic pack product key is in BIOS and the hard disk has a hidden partition where the OS backup is stored.
Now I bought Win 8.1 enterprise key. I have plan to buy new desktop machine and I am going to install the enterprise OS into it. Until I buy a new machine, I want the enterprise os to run in my laptop.
I want to install it either by USB boot/DVD or through directly mounting the image and installing the setup, without cleaning the OEM setup or cleaning the hidden partition, so that I can restore anytime to basic pack.
I have searched the solution, but can't find out. Help needed! Please help..
