How to Remove “Earlier Version Of Windows” 

IN Windows 7 Bootloader with “bcdedit” command

line utility If your computer has more than one OS installed
natively on the system and Windows 7 is one of
them, the chances are, you will see the options to
boot into other “Earlier Version Of Windows”
option during the system startup.

So what if the previous Windows OS (doesn’t
matter if it’s Windows Vista, XP, 2000 or even
older edition) is already removed from the system
but for some reason the boot loader didn’t get
updated? You basically are seeing this option
showing up every time when you turn on the
machine.

Here’s how you can delete the unnecessary boot
loader entries and straight boot into your
Windows 7

Firstly, you need to boot into Windows 7.
Open up the command prompt and type “bcdedit ”.
Make sure you are running the command line as
Administrator .

Here is an example,

 Everybody might have
different results when you type the command.

Basically, it lists out all the OS that has
registered to the Windows Boot Manager.

 For
instance, as you can see, there is an entry called
“Windows Legacy OS Loader”, the identifier of
which contains the value “{ntldr}”.

 From this, I
can tell the Windows Legacy OS Loader used to
load Windows XP on this system, since the value
of ntldr is default for winxp bootloader.
Now type bcdedit /delete {ntldr} /f
After you see the message “The operation
completed successfully”, and restart your
computer, you will not see this boot option any
more during the next startup.

“bcdedit” is a powerful command line utility that
manages your Windows boot loader. You can not
only clean out unnecessary boot entries, but also
can create new boot entries manually as well. For
more information about how to use the tool,
simply type bcdedit /? for help. 

But be more
careful about what you will be doing there, as any
entry deleted through this command will be
extremely difficult to recover.
