Lenovo H500S Bios Update – How To

Well folks, today I’ve encountered a big problem trying to upgrade a LENOVO H500S bios. First of all, you have to know that Lenovo support is missing, at least for this model. But I’ve found out a solution so you can upgrade the bios and be able to boot Windows 7, Windows Vista, or Windows XP on this machine type. Here is a photo of the old BIOS model:

For some reasons, Lenovo doesn’t put too much effort in releasing a hassle-free method for the user. But here is what I’ve found, and if you are in the same situation (Bios upgrade) and want to install another operating system, just follow these easy steps:

  1. Download the Make_PE3_48.exe file (don’t worry, it’s virus free, but for your peace of mind, scan it anyway).
  2. Start the file
  3. Select where you want to create your ISO file (all the content will be extracted from your current operating system if you don’t have an iso at hand – which was my case).
  4. When the entire operation is completed, download the RUFUS bootable USB maker from here
  5. Select the ISO previously created by the Make PE3 file, at the step 3 and make the USB bootable.
  6. Download lenovo H500S Bios Update File
  7. Uncompress the archive and move it to your newly created Windows PE usb stick.
  8. Boot the Lenovo H500S using this stick newly created at the previous steps.


9. Start the software to upgrade the Lenovo H500s BIOS.

When the entire process is completed, just reboot the machine and use your regular image to install the operating system of your choice (Windows 7, Windows Vista, Windows XP, etc).
