Windows 7 Reinstall on a Lenovo W520

Just thought I'd post some quick notes on doing a Windows 7 reinstall on my Lenovo W520. I'll go over some useful tools and some frustrating problems I encountered and how to avoid them.

First off, useful tools:

  • Windows 7 SP1 AIOis an all-in-one Windows installation image meaning it includes all the versions of Windows and gives you the choose of which one you want to install.
  • Advanced Tokens Manager allows you to backup the activated status of your existing Windows and Office installations. This is extremely useful because you no longer need to worry about product activation or finding your Office license.

Getting Ready

Start out by running Advanced Tokens Manager to backup your currently activated licenses for Windows 7 and Office. Make sure you copy this off of your computer onto a USB stick (or if you have two hard drives in your W520 like me you can just move it onto the other hard drive.

Next make sure you have no data on your Windows installation partition. Make sure you check not only your My Documents, Pictures, etc. but application settings such as FTP client's saved logon information, save games which tend to be in stupid locations, and internet browser settings (use Firefox or Chrome's sync features).

Prepare your installation media, for me this meant making a spare USB stick bootable and extracting the Windows 7 AIO ISO onto it. It also doesn't hurt at this stage to download the latest drives from and extract them onto a USB 2 stick (make sure you extract them, they come as self extracting EXEs which Windows cannot use to find drivers).

Doing the Reinstall

Put the USB stick in one of the USB 2 ports (the eSATA+USB combo or the always on USB) and reboot the computer. Press the blue ThinkVantage button and choose to boot from the USB stick.

When the message appears, press any key to start the installer.

Choose the correct edition of Windows to install and make sure you select Clean install. Windows should see your existing hard drive(s) as it appears to be able to use the drivers on the existing hard drive (if you've already erased your partition you might have to select the Intel storage driver from a USB stick). Once I've selected the correct hard drive I like to delete all the partitions off of it and let Windows recreate them from scratch. You may want to keep the existing Lenovo recovery partition but I had already removed mine.

At this point, you're ready to proceed with the install. Let the Windows installer copy the files and then fill out the information after the reboot. Note: You don't have to enter a license key! Just leave it blank and let Advanced Tokens Manager handle it later.

Setting up the OS

Once you've got to a Windows desktop for the first time make sure you install a few key Lenovo drivers before doing any Windows Update.

First off install the Intel wired network drivers followed by the Lenovo display drivers. The Lenovo display drivers must be installed first or Windows Update may install an Intel video driver which will cause a BSOD reboot loop. Once the Lenovo display driver has been installed you should be able to download the rest of the drivers from and run Windows Update as you please. If you plan on doing any gaming make sure you get the latest NVIDIA Verde driver off, it will be fully compatible with the Optimus switching.

Once everything is updated go ahead and restore your backed up Windows and Office activations using Advanced Tokens Manager


Thank you for posting this article. I need to reinstall Windows 7 on a Lenovo G530 PC. Where can I find a Windows installation image to use?

Thank you.

I hve been configuring Lenovo W520s for quite saome time using a USB drive with a WIM image on it. After I boot the USB has always been accesible as the E: drive. All of a sudden on a new machine after I boot from the USB it shows up as the C: drive. Since one of the first thing the boot image on the USB drive does is format C:. Since the USB drive is now C: it format's itself! Lenovo has replaced almost everything in this machine but I have the same problem. Can someone help?

Very cool tip!

I need all the help I can get with my computer so thanks for the tip. I'm a mess when it comes to doing work on my laptop.

Lenovo has been using windows seven for the students. All the features have been visited on boomessays for the utilization of the goals or the people. The actual reel has been used for the observance on all parts or the mobiles.

Super Fun Time
