Today I want to share a solution to the problem I experienced when I dualboot Operating System. Sometime I want to delete one of them but…when I deleted one of them, the bios boot option will still detect the OS that was deleted earlier. So how do i remove it?

Step by step:

1. Firstly open terminal as Administrator

Then type:

bcdedit /enum firmware

2. See the list and find the OS identifier you want to delete

3. Delete firmware of OS

Then type:

bcdedit /delete{identifier}

It’s Done…
