Remove Ubuntu Bootloader code from Windows 10

Hello folks, I am back with yet another post in the Solving Technical Series. In certain situations, when a program you want to run does not work properly on an OS, you first blame the program. Then you try to run it on another OS, and find it working without issues. Then you go back and blame the OS. This is what happens to me when I try to run the Android Studio Emulator on Linux. Its screen size remains small despite resizing. Resizing works fine for Windows 10.

As I am a part of the FOSS Club of my college, I know that I must be embracing Open Source Software, but in certain situations like these, my head just gets fried up.

So one fine day, I decided to remove Linux from my PC. I removed those Linux partitions, but unfortunately the Ubuntu Bootloader (aka GRUB) was still present on the Boot screen. Then I had to find a way to remove it from Windows. And voila, there is a way out.


  • Open Command Prompt as an Administrator.

  • Now enter diskpart on the CMD screen

  • Now enter list disk. You will see your Hard Disk and the external storage drives connected to your PC. Select the PC Hard Disk Number. It should be 0 by default on all the systems. But still, check your hardware and then do.

  • Select Disk 0 (or whatever number it is of your HDD) by typing sel disk 0. Now to check a list of partitions in it, type list vol

  • On 64 bit systems, it should be a 100 MB FAT32 system that has ‘System’ as the Info in it. Note the volume number. In my case, it is 9

  • Type sel vol 9.

  • Now this volume has been selected. We now have to assign the disk letter (for which Windows/MS-DOS became famous for). I assigned a letter Z, by typing assign letter=Z:. Then exit diskpart.

  • Now you are back to your regular CMD Prompt. Now type cd /d Z:. Note the /d arguement.

  • Now for this step, there are two ways to approach this. Some systems will have the ls command, while some won’t. While I would recommend using the ls command, for those who don’t have it can use the dir command as well. Type ls or dir, depending on the program you have

  • cd into the EFI folder. Then type ls again. You will now see a Ubuntu option.

  • To remove this Ubuntu GRUB, type rmdir /s Ubuntu. It will ask for a confirmation Prompt, type Y and press Enter.

  • Voila! Your PC won’t have the Ubuntu Bootloader anymore.


Sometimes, at any given point of time, any given OS can be frustrating. Choose your OS depending on the features you need.


Android Studio 2.3 Update on Linux fixes the issue I had. So I am back on Linux. Hell Yeah!
