Removing dual boot in Windows 7

If your computer has more than one operating system (OS) is installed natively on the system, and Windows 7 is one of the operating system, I'm sure you'll see the option to boot into another operating system such as "Earlier Version Of Windows" on system startup.

So what if the previous Windows operating system (no matter whether it's Windows Vista, XP, 2000 or even older editions) has been removed from the system, but due to some problems the boot loader can not be updated? Basically you look at these options every time when you turn on your computer.

Here is how to allow you to remove entries that do not need to boot loader and boot directly to Windows 7.

First of all you have to get used to the system Windows 7.

1. Open a command prompt by Start>> Run>> CMD>> Enter.

2. Once the Command Prompt open a typed bcdedit.




Here is an example. Everyone may have different results when you type commands. Basically all the list of OS that have been registered to the Windows Boot Manager. For example, as you can see, there is an entry called "Windows Legacy OS Loader", the identifier that contains the value "NTLDR ()". From this, I can tell Windows Legacy OS Loader is used to load Windows XP on this system, because the NTLDR is the default for WinXP bootloader.

3. Now typing bcdedit / delete {ntldr} / f.



Once you see the message "The operation completed successfully", restart your computer. And you will not see the boot option again during the next startup.

"Bcdedit" is a powerful command line utility that can manage your Windows boot loader. Not only can you clean up the boot entries that are not necessary, but can also create a new boot entry manually. For more information on how to use the tool, type bcdedit /? for assistance. But be careful about what you would do in the utility, because any removal operation will be very difficult to meulihkanya.
