lets get to the point ^^

my friend have a laptop that have installed windows 7 and re-install windows with windows 8.1 by wiping the drive first. but strangely, the laptop is dual booting everytime it is turned on. he have to choose between windows 7 and 8.1. but when he chose 7 there's nothing happened just blank black screen.

the question is:
can we remove this seemingly dual boot feature? if we can, then how?

thanks in advance

He didn't 'wipe' it fully. The boot partition is probably still there from the original Win7 installation. Now it contains both.

You can remove the non-existent Windows 7 environment from the BCD using BCDEdit. Use /enum to enumerate the existing entries in the store and use /delete {identifier-GUID} to delete the entry with Windows 7 under the description. These commands will need to be run from an Administrative Command Prompt (or PowerShell), see How do I run a command with elevated permissions.
