Removing an entry from the BOOT LIST in Windows 7 using Boot Configuration Data Editor (BCDEdit)

Dual booting two operating systems is a cool way to manage computer resources, however if you get back to single boot, the Boot record could still be showing the previous Instances. In my case I was installing Kali Linux using the Debian setup that sets up the environment of installing the Linux Operating System to dual boot with Windows 7. The Linux OS installed successfully but the Debian GNU/Linux - Continue with install process entry remained in the Windows boot record.
To remove one entry so the windows boot directly without prompting me to choose an instance, this is the process

Run the Command prompt as Administrator, 

Type BCDEdit to display the running configuration of the boot loader.

  

This displays the instances of Operating Systems Installed in the computer and a present in the Boot Loader configuration.
To remove the unwanted entry; Debian GNU/Linux - Continue with install process in my case;
Type BCDEdit /delete {boot loader identifier}; In my case BCDEdit /delete {934f384a-f4a8-11e3-9b19-f0b1fa384968} then press enter.

 





















  








The entry is deleted from the boot loader configuration and the you wont be prompted to choose operating system to continue with during boot process.
However exercise caution when entering the boot loader indentifier because if the Windows identifier is entered during this process the Operating System may be rendered unbootable.
