"boottrec /fixboot" command says "access is denied" -Windows 10 (NOW FIXED)

I was wanting to remove the Ubuntu distro from my Windows 10 laptop, so I followed the advice from this article: 

https://www.makeuseof.com/tag/how-to-safely-uninstall-ubuntu-in-windows-dual-boot-environment/

I followed the advice to the point where it told me to go boot from the Windows 10 installation disc (I used a USB) and enter the commands in the command line:

"Restart to boot from the installation disc, and clickRepair Your Computer. Next, select Troubleshoot > Advanced Options > Command Prompt. Here, we use the Bootrec.exetool using the fixbbr command."

First I put the command bootrec /fixmbr in. It worked good. Then I put in the command bootrec /fixboot and it said "access is denied".

bootrec /scanos and bootrec /rebuildbcd worked good otherwise, but /fixboot is the one I have trouble with.

And for the record I did see this forum post with the same problem but with a different scenario : 

https://answers.microsoft.com/en-us/windows/forum/windows\_10-performance/windows-10-bootrec-fixboot-access-is-denied/747c4180-7ff3-4bc2-b6cc-81e572d546df

And I found the answer very confusing. So hopefully this picture can help you give me the correct commands to put in:

Note: (C:) is my Windows partition, the Unallocated one was Ubuntu

Edit: The problem is now fixed. All it took was a quick reinstall of Ubuntu.

    Yes, but I most likely did it wrong. Is this right? (Remember: (C:) is my Windows partition)

    Did you try using the EasyBCD utility to delete it?

    I followed your advice and now the partition previously used for Ubuntu has been combined with my Windows partition.

    However, every time I turn on my computer the Command Prompt for the GNU GRUB still appears. Luckily I could just type exit and go to the boot menu. That way I can boot into Windows.

    Still though, this is quite an annoyance.

    The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition (C:). Right click the ‘Healthy Boot drive C:\ then click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

    A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

    The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.

    Too remove any boot managers for Linux, use the free EasyBCD software from Neosmart:

    Download and install EasyBCD. Don't worry, it's free for non-commercial use.

Go to the BCD Deployment tab.

Select the correct version of the Windows boot loader for your computer (Windows 7/Vista or XP).

Click Write MBR.

Go to the Edit Boot Menu tab and make sure your Windows installation is listed there correctly.
