How to Find Your HP Notebook's Exact Serial Number for BIOS Updates

Select Language:

If your HP notebook is over 10 years old, support for it has been discontinued, which is why you might have trouble finding information or updates for it. Typically, updating the BIOS isn’t going to fix most issues with old systems like this.

One important step is to see if you can access the F9 boot options menu. This allows you to boot from an external device, like a USB flash drive, to install Windows on a new hard drive. To do this, turn on or restart your computer. As soon as it begins to start, keep pressing the ESC key repeatedly until the menu appears. From there, select the F9 boot options. You should see a list of boot devices; choose the USB flash drive and press Enter. This will make your PC boot directly from the Windows installation flash drive.

If you need to update your BIOS, the last update released by HP for your model is version F.43. You can find the download link and the executable file here:

Since your device currently doesn’t have an operating system, you’ll want to create a BIOS recovery flash drive using another Windows PC. There are helpful videos that guide you through this process:

Following these steps should help you boot from a Windows installation drive and update your BIOS safely, even without an operating system installed on your device.
