On Unified Extensible Firmware Interface (UEFI)-based computers, firmware creates non-volatile random access memory (NVRAM) entries for local devices (such as Optical Disk- or Hardisk drives) when the computer boots. BCDEdit synchronizes the firmware namespace object in NVRAM with the system boot configuration data (BCD).

In case there is more than one Windows installation or another type of OS has been installed (for example Linux OS installation) on the computer, additional bootloader entries are created and shown in the boot manager list. This document describes how to remove unwanted entries on Windows 10 using the BCDEdit command.

 

IMPORTANT INFORMATION Please note, in case a still required bootloader entry will be deleted, the related OS won't boot anymore. Be sure, to delete only unwanted and not necessary entries. It is recommended, to use the  BCDEdit command "BCDEdit /export" to save a copy of the current system storage before deleting any entries.

   HOW TO REMOVE UEFI (NVRAM) BOOT MANAGER ENTRIES ON WINDOWS 10

1. Type "cmd" in the Start menu search bar
   
2. Right-click Command Prompt and select Run as administrator
   
3. Once the elevated Command Prompt window opens, type "bcdedit /export c:\backupname" to create a backup of your BCD settings
   
4. Next, type "bcdedit /enum firmware" to list the current stored boot loaders entries:
   
   
   
   
   
5. As shown in the picture above, copy the whole identifier of the boot menu entry, which should be deleted.
   
   For example, the whole identifier of the picture above is as follows: {44613cea-f482-11e8-bb6d-db9e25b6bad3}
   
   
6. Now, type "bcdedit /delete identifier" to delete the boot menu entry in question.
   
   For this example, the command would be as follows: "bcdedit /delete {44613cea-f482-11e8-bb6d-db9e25b6bad3} "
   
   
   
   
   
7. The unwanted entry has been deleted
