Switching to Ubuntu, how to restore windows partition?

Question

ubuntu

Generally summer, rain. I decided to do something useful and dump Windows 8. I made a 100GB partition and installed ubuntu 14.04 LTS, poked around, looked at the main commands in the console, looked at the software that I used on 8rk. Everything suits and I decided to reinstall ubuntu again (the first time when installing on a partition, I did not specify a swap partition or something and the installer cursed) and foolishly clicked to remove ubuntu and install, that is, everything under clean. But the problem is that I have a Lenovo Z500 laptop and there was an image of Windows (recovery or whatever) and it seems to have disappeared :( I wanted to know if the keys were left from Windows?

Answer 1

You have a key embedded in UEFI.
Most likely, you don’t have Windows and recovery there, so in order to install a licensed version of Windows, you will have to first determine which image you had originally, this is done using special utilities. You find out the Windows product key through some kind of Linux utility and determine what Windows was before through the site: link .
Then you find an image similar to what you stood and put .... Google is better for more details.

Answer 2

Windows keys are usually on a sticker on the outside, at the bottom of the laptop itself.
