Will I Have to Reinstall Windows If I Update BIOS?

I use an ASUS computer. I recently set everything up and looked for drivers on the ASUS support website. I see that the BIOS needs a new update. Will everything return to stock if I flash the BIOS, and will I have to reinstall Windows? Thank you in advance!

The short answer is No. Updating BIOS will not delete anything on your computer, neither your data nor your Windows. Therefore, you do not have to reinstall Windows after the BIOS update.

Flashing BIOS will only cause the BIOS to its default settings; it will not change anything on your computer. However, if a problem arises when updating the BIOS, you might be unable to boot into the operating system any longer. Although this is not particularly often, it could result in data loss.

Therefore, taking actions, like backing up your computer, before updating BIOS is always recommended to prevent any potential data loss. This is because this can make sure that you will not lose anything in case of a BIOS update failure.
