If you're running legacy mode (not UEFI), there's a way to change the boot logo by editing the resources in the file called bootres.dll. Note that it's not a very easy thing to do, and it will most likely require you to run Windows in 'test mode' that doesn't verify digital signatures in order to allow the system to use a modified bootres.dll.

Now we create/edit a Bios-Boot-Logo. In this example i use the graphics program PaintShopPro from Corel, but you can use your favorite program as well. Replace the startup logo The only supported way to replace the startup logo with a custom logo is to modify the Boot Graphics Resource Table (BGRT) on a device that uses UEFI as the firmware interface. If your device uses the BGRT to include a custom logo, it is always displayed and you cannot suppress the custom logo. Add Change Manufacturer Information by Editing the Registry Manually. To change the manufacturer information for your PC in any version of Windows, you just need to make a few edits in the Windows Registry. Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable.

However, since the Windows 10 Anniversary Update (v1607), the OEM logo has been deprecated and not displayed on the Settings page. This logo appears in the classic system information or Performance Information and Tools Control Panel, but is not used in the Settings app.

BIOS-Bootlogos

A short instruction, how to create EPA BIOS-Boot-Logos and Fullscreen BIOS-Boot-Logos under Bios-versions from AMI, AWARD and PHOENIX, with Bios-Tools like: AMIbcp, AMIFlash, AWDFlash, WinFlash, WinPhlash, CBROM, and my Freewaretool BMPtoEPA.

Extract Boot-Logo out of BIOS Update file

Bios-Tool: CBROM v2.15

CBROM, a small software from AWARD (PHOENIX), has functions to read, edit and insert each segments inside a Bios Update file. CBROM works under DOS and the Windows command line. To show all parameters, go to the command line (DOS-Prompt) and insert: 'cbrom215.exe'.

First of all we need a Bios Update file to edit the current logo, and the parameter /D to show all ROM segments. In our example we use the BIOS Update file 'N24LD505.BIN' from the DFI mainboard 'LanParty NFII Ultra B'. The input of 'cbrom215.exe n24ld505.bin /D' shows:

The picture above shows the small EPA-Logo (EPALogo.bmp) on Pos.10, and the Fullscreen logo (LanParty.bmp) on Pos.11, and also the original and compressed size in kilobytes.

EPA-Logo extraction:
Extract the small EPA-Logo with 'cbrom215.exe n24ld505.bin /epa extract'.

Fullscreen-Logo extraction:
Extract the Fullscreen with 'cbrom215.exe n24ld505.bin /logo extract'.

Insert Boot-Logo into BIOS Update file

Bios-Tool: CBROM v2.15

Now we use CBROM to insert our self created (normal) Bitmaps. Because CBROM is able to translate normal BMPs into the special AWBM format. All we have to do is to create (see below) a Bitmap file in a specified size and format.

EPA-Logo insertion:
'cbrom215.exe n24ld505.bin /epa filename.bmp'

Fullscreen-Logo insertion:
'cbrom215.exe n24ld505.bin /logo filename.bmp'

If you get an error message like 'not enough space!', you have to edit your Bitmap a second time with a graphics program either to reduce the Bitmap size, or to use less colors as a result to get a better data compression.

Create Boot-Logo with Paint Shop Pro

Now we create/edit a Bios-Boot-Logo. In this example i use the graphics program PaintShopPro from Corel, but you can use your favorite program as well.

The different formats for Fullscreen and EPA-Boot-Logos:

Customize OEM Support Information In Windows 10 | Tutorials

Start PaintShopPro, create a new file and choose one of the above formats with the right resolution and color depth.

During your first tries: use black as background and white as foreground color. After you have created your logo, save the Bitmap file (BMP) without RLE-Compression.

Disable Boot Logo Windows 10

Fullscreen-Logo: start CBROM to insert the Bitmap into your Bios-Update file.

EPA-Logo: start the Windows tool BMPtoEPA, convert the Bitmap into the EPA-format, save it and use CBROM to insert the Bitmap into your Bios-Update file.

Finally write the Bios-Update file onto the Bios-Chip.

Boot-Logo Software (CBROM, Flash tools)

CBROM Download: www.award.com or Google

Version info:
CBROM-Version: 1.x for Award v4.x (old)
CBROM-Version: 2.x für Award v4.51+v4.6x (old)
CBROM-Version: 6.x für Award v6.x (new)

Use the flash tool from your mainboard manufacturer to program your Bios-Chip!

Write BIOS Update file onto BIOS-Chip

Please read my Bios-Update-Instruction or use the instructions from your mainboard manufacturer.

Anytime you boot your Windows computer, the very first thing you see on your screen is the manufacturer’s logo. I don’t know about you but I’ve always wanted to change just about everything on my Windows PC ever since I got the customization flu. The boot logo though is not as easy as changing the wallpaper or even the Windows login screen. The manufacturer doesn’t want you to change the logo. Although, Windows is a pretty popular platform. When a lot of developers have something, somebody will always find a way to change the Windows 10 boot logo. That is how we have this nifty tool called HackBGRT. It lets you change the Windows UEFI boot logo.

Change Windows 10 Boot Image

Warning

HackBGRT is a little complicated to use. Also, you’re not using it to change wallpapers. Remember, Windows is an OS that might fail to boot when you try as much as installing an icon pack. Changing the UEFI Boot logo is something at another level. It’s our duty to let you know that if you do proceed with using this tool your PC might fail to boot. It is unlikely if you’ve followed the guide below carefully but still very possible. We recommend creating a recovery media first or at least a system restore point. You can create a Windows system restore point and use it to restore your PC.

HackBGRT also creates a backup of the bootloader for such situations. We’ll show you how to use that as well.

Requirements to Chane UEFI Boot Logo

Unbranded Boot | Microsoft Docs

HackBGRT only supports UEFI systems and is not meant to work on anything else. If you’ve bought your computer recently, it is more than likely to support UEFI. If you’re running a dual boot setup, you’re most probably using the Legacy bootloader, in which case you can’t use this tool. You must also make sure Secure Boot is disabled. This can be done in the BIOS menu accessing which is different, depending on the manufacturer of your PC.

Download

Steps to Change Windows 10 Boot Logo

1. Download the latest HackBGRT zip from GitHub using the link above and extract the archive.
2. In the extracted folder, double-click on the setup.exe file. If your system doesn’t support UEFI or you have it turned off you will be told so in the command prompt window that opens up. Similarly, you will be asked to disable Secure Boot if you have it enabled.
3. Hit I on your keyboard to begin the installation. After that is complete the program will open a configuration file in a Notepad.
4. In this configuration file, you’ll be required to specify the path to the image file you want to use, the positioning of the image on the screen, etc.
5. When you’re done with it, save the configuration file and close it. The default boot logo will then be opened in an MS Paint window. You can edit the image or copy from another source, then save the image in 24-bit BMP format.
6. Once the image is saved, the program will make the necessary changes and your boot logo will be applied. You can see the changes when you reboot your system.

How to revert changes

Did something not go as planned? Launch the setup.exe file again and hit D instead of I this time in the command prompt window. There is also the possibility that you might not be able to boot into your system. This is quite unlikely, but we did warn you before. If you did create a recovery media or already had one, you can use that. Or you can use a Windows system restore point that you may have created.

Since you aren’t able to boot into the system, you may still need a bootable Windows media, such as a disc or a USB drive. You can also use the backup created by the HackBGRT tool by copying [EFI System Partition]EFIHackBGRTbootmgfw-original.efi into [EFI System Partition]EFIMicrosoftBootbootmgfw.efi. To do that you will need to use the command prompt from a Windows media or use an Ubuntu Flash drive, etc.

Having applied a custom boot logo on your PC, you might also want to install a custom theme on your Windows 10.
