I have a Thinkpad X201 with a new HDD, so the original Windows installation has been lost. What is the easiest way to reinstall Windows on the new drive (and ideally reuse the Win 7 pro license - there is a label at the bottom of the laptop)?

Download ISO file of Windows 7 pro from below links:

  1. Windows 7 Professional English 32-bit
  2. Windows 7 Professional English 64-bit

Now burn the ISO file to DVD or USB ( minimum size of 4GB required ), You can use Windows 7 DVD/USB tools to burn your iso, you can download it from this link:Windows 7 DVD/USB tools

Now boot your PC from DVD/USB and install/reinstall your windows and give your Product key from COA sticker located on back or side of PC tower, bottom or under battery of notebook.
