When you install multiple version of Windows, it creates an extra entry during the Bootup. It helps you selecting the right OS to boot. If you plan to remove one of the versions, and want to make it simple, then here is a simple trick to remove multiple Windows entries from Boot Menu.
Usually, this may happen when you are upgrading Windows, and the old entry remains. The first one is one which you had recently installed. The other is the one you were using before the upgrade. Each of these menus should be saying “Windows 10 on Volume 2” or “Windows 10 on Volume 4” where numbers can change.

- It will launch the System Configuration. Now switch to Boot Tab.
- Here, you should see two Windows installation. Now depending on the drive where the previous Windows was installed, select it. Make sure to double cross and choose the correct one.
- Once sure, hit the delete button and check the option which says “Make All boot settings permanent.”
- Exit and restart your computer to check if it worked.
Again, make sure you are removing the correct older installation else it will be challenging to bring back the new installation.
