Change Boot Logo

Important: If you mess up the installation, your system may become unbootable! This software comes with no warranty. Use at your own risk.

• Make sure that your computer is booting with UEFI (Very likely that you do)

• Make sure that BitLocker is disabled, or find your recovery key.

• Create a full backup or a rescue disk before making any changes to the Windows boot logo. The backup or rescue disc helps you restore Windows if something goes wrong and you are unable to boot.

Setting the logo

Note:

• You cannot set GIFs or transparent images as the new boot logo.

• Keep the background of the logo black as transparency is not supported. Therefore, the new logo doesn’t look out of place on the black background of the boot screen.

• The image should not be bigger than 300 x 300 pixels. While the size is not a strict requirement, it ensures that you will not face problems while setting the new boot logo.

1. In Paint, click on the File > Import from Canvas > From file option. Now, find the image you want to set as the new Windows boot logo, select it, and click on the Open button.

2. If you want, you can resize the image by clicking on the Resize button.

3. Once you are done, click File > Save to save the file. After saving, close the Paint application.

4. Press a key to exit the cmd window.
