You may need to uninstall ubuntu completely from a dual boot system for various reasons.

1. Installing Ubuntu From Windows 8

The wonderful Ubuntu terminal is freely available for Windows 10. As any Linux user knows, it's the command line terminal where the magic happens. It's perfect for file management, development, remote administration and a thousand other tasks. The Ubuntu terminal for Windows has many of the same features you'll find using. Apr 28, 2014. There are three ways to have your Ubuntu and keep Windows, too.

If you were using Ubuntu regularly, then there may be some important files, it's wiser to take a backup of those files first.

So, here's how you can uninstall ubuntu dual boot without Windows installation USB or CD. It could be done in two ways(or 3, depending on your system), either from Ubuntu or from Windows.

It's rather easy on UEFI based systems, if Windows 10 was installed with UEFI compatibility, let's get started.

Uninstall Ubuntu step by step

To remove ubuntu dual boot you need to follow the steps below one by one. All these steps are done within the Windows 10 installation.

1. First open up the command prompt as Administrator.
2. Next set the correct EFI executable as default boot entry. For that, you need to run the exact command below. Alternative method here.
3. If the above command was successful, then reboot聽your PC to check if it's booting straight to Windows or not.
4. If it's booting to windows normally, then it's time to delete the linux partitions and recover that free space.
5. To delete the linux partitions,聽Press the Win聽+ R key combo and type diskmgmt.msc to start聽Disk Management tool.
6. Select the correct hard disk and identify the Ubuntu partitions.
7. Now delete all the identified linux partitions. Select the correct partitions and right click on them, and hit the delete volume option.
8. Apparently you have two choice, either use this free space to extend an existing windows partition, or leave it to dual boot linux in future. But for now, I'll choose the first option.
9. Extending an windows partition is fairly easy, assign all the free space to the extending volume.

Alternative method to change boot order

As we're dealing with a UEFI system, we can change the UEFI boot order directly from the UEFI firmware setting, i.e. the BIOS settings. Of course for that, you've to enter your PC/laptop's BIOS settings while.

Tap or hold the BIOS setting key while restating your system, in my case it's F2 key. Which might be different on your system, like the Esc or Delete key.

Then go to the boot selection menu, again this could be different on your system, but you got the idea.

From there you can select the UEFI boot priority, select Windows Boot Manager as first priority.

From there you can directly boot to Windows 10 without typing the bcdedit command.

Troubleshooting

Check the point 3 in the above list, if you're still booting to GRUB, then you may need to fix it within Ubuntu with efibootmgr command line tool.

I'm not going to very details, but what you've to do is change the UEFI boot order with efibootmgr command.

First check the default boot order with only the efibootmgr command.

Next you need to put widows first in the EFI boot entry, for that you need to run the command below on Ubuntu.

Note: Your efi boot entries could be different, don't just copy paste the above command.

Uninstall ubuntu and GRUB: This step is totally optional, but required when you need to remove every part of linux, as the EFI system partition is untouched in this tutorial.

To remove ubuntu grub you need to mount that partition on Windows and remove the entire Ubuntu directory with windows commands. Alternatively you can use a linux live USB and mount the EFI system partition to remove the Ubuntu directory.

Conclusion

That's all about how to remove ubuntu from dual boot system, hope it's simple enough to understand. You can read more about windows boot manager here.

This exact same method could be used with any windows-linux dual boot system, not limited to Ubuntu only.
