Use bcdedit to delete multiple Windows systems

I installed a Win8 preview on my office computer a few days ago. Now I want to delete it and I don't want to affect my original Windows 7.

So google found the bcdedit (Boot Configuration Data Edit) command.

The process is simple:

0 open cmd as Administrator

1 bcdedit // display a bunch of items and find the ID of the system to be deleted

2 bcdedit/delete {ID_TO_DELETE}

 

Bcdedit was introduced from Vista and does not support the XP system!

For more information about bcdedit, go to MSDN:
