BIOS Update Will Not Detele Anything

The BIOS is one of the very low-level systems on your computer and controls many important features, such as booting. BIOS updates are usually provided to fix flaws in the BIOS's programming. A BIOS update can sometimes improve performance if something is wrong with the old version, but usually, it fixes bugs.

Besides, it can support new hardware. If you plan to upgrade or use recent hardware and a new BIOS can support it, but the current version does not, at this time, you need to update your BIOS. But does BIOS update erase data, or will the BIOS update delete files?

The short answer is NO. Updating the BIOS will not harm your data in any way. In addition, flashing BIOS will cause the BIOS to be reset to its default settings, so it will not change anything on your HDD or SSD.

However, if you encounter an issue when updating BIOS, you might not be able to boot into OS anymore, which could potentially result in data loss, though it is not very common. In that case, you may even render the computer inoperable until you replace the BIOS chip with a new one.

Therefore, taking precautions, such as backing up your computer, before flashing BIOS is always recommended to avoid any potential data loss. How to back up your computer for data security? Keep reading!

How to Backup Your PC for Data Security

Before updating the BIOS, back up all of your essential data to an external drive or cloud storage service since this can ensure that you will not lose any data in case of a failure during the BIOS update process.

When backing up your computer, you can create a system image. For that, you can use Windows Backup and Restore (Windows 7). But it is worth noting that Backup and Restore cannot offer advanced backup options, such as Cloud backup. Therefore, it is better to use third-party backup software like EaseUS Todo Backup.

EaseUS Todo Backup Home is a multi-functional and practical backup program. It can let you back up the systems, files, partitions, computer apps, etc., and back up multiple hard drives simultaneously. In addition, it allows you to create various backup modes, including automatic, scheduled, full, incremental and differential backups, to meet your differential backup needs.

Why is EaseUS Todo Backup so recommendable? Here is the answer.
