Yes, it is safe to update your BIOS; when updating BIOS, you will not lose anything on your computer.

Your data have nothing to do with the BIOS. The BIOS is only concerned with hardware settings, such as CPU overclocking and boot performance.

Some motherboards include a built-in fail-safe that will immediately re-flash a stable version if a BIOS update fails. The worst-case scenario is an unbootable PC if your board lacks this feature and the BIOS upgrade fails, which may potentially cause data loss in this case.

In addition, a power outage or other disruption could cause issues, so you should also ensure your computer is connected and has a reliable power supply when updating. It is crucial to obtain assistance from a knowledgeable technician or the maker of your computer or motherboard if you are unclear about updating your BIOS correctly or having problems while doing so.

No matter whether it will cause data loss to your computer when updating the BIOS, it is highly recommended to back up your data before flashing BIOS. This is because precautions are always much better than cures.

To back up your data, the best way is to use a professional backup tool like EaseUS Todo Backup since such a tool can offer you more backup options and functions.
