Steps to remove dual boot in Windows:

If you’ve properly installed a second operating system on your computer, there’s probably a folder containing its files on a separate partition. First step of getting rid of the second OS is as simple as deleting that folder. If you’ve been really smart and also installed all programs for that operating system in another partition, away from the program files of your primary operating system, then it’s wiser to just format that partition. In case your program files are mixed up, you will have to manually delete them.

Now, to remove the prompt at the boot screen, here’s what you need to do:

Step 1: Go to Start menu.

Step 2: Click Run (in case of Windows XP, Vista and 7) or right click the bottom left corner and click Run (in case of Windows 8).

Step 3: Type “msconfig”

Step 4: Go to the Boot tab. You should see your operating systems listed, with one being the Default OS. If the Default OS isn’t the one you want, simply highlight your primary OS and click “Set as Default”.

Step 5: Now highlight your secondary OS and click “Delete”.

That’s it, now your PC won’t prompt on boot to select an operating system. You can also use this menu to change how much time the OS select screen is displayed. Let us know if you have any other queries on how to remove dual boot in Windows and of course, comments and suggestions are welcome!
