Updating a bios in windows
In the System Information window which appears, select System summary on the left and look for the entry BIOS Version/Date on the right.Head to the motherboard or laptop manufacturer's website and look for a support link.
They do vary, and you may need to configure some things before starting the update process, such as disabling secure boot modes and fast boot modes.It's good to have a spare copy of all important files from your PC before you start.Though a failed BIOS update doesn't endanger the data on your hard drive directly, you will be able to access your files and continue working with them on another PC or Laptop without delay if you have a backup on a removable drive.Similarly, creating a backup of your BIOS is also a good idea.Sometimes this will be done automatically as part of the updating process, but if it requires you to do it manually, be sure not to skip this step.If there's a power cut, or the computer gets turned off while updating, it could mean that it's unable to boot at all.
For this reason, it's worth checking whether you really need to update your BIOS.
Sometimes you will need to update the BIOS in order for the motherboard to properly support a new processor or other hardware, or to fix bugs and improve stability or performance.
In most cases, nothing will go wrong at all, but it's important to know that there's an associated risk and not to treat the process too lightly.
Note: Occasionally you will need to install a previous version before updating to the latest version.
This info is usually found in the "Important Information" section.
If the recovery key is not known this can result in data loss or an unnecessary operating system re-install.
