Brief: This beginner’s guide shows you how to safely remove Ubuntu from Windows dual boot.
I’ve covered how to install Ubuntu in dual boot with Windows several times in the past. But what about uninstalling Ubuntu from Windows dual boot? The tutorial we’re going to follow here applies to any Linux distribution, be it Ubuntu, Linux Mint, elementary OS or any other version.
If you think installing Ubuntu with Windows in dual boot was a tough task but it will be very easy to remove Ubuntu from Windows dual boot, you’re not totally wrong. Uninstalling Linux from Windows dual boot is a piece of cake if you have a Windows installation disk.
This tutorial teaches you how to remove Linux completely from Windows 8.1 or Windows 10 dual boot with a Windows installation disk.
Uninstall Ubuntu safely from Windows dual boot mode
You need to have a bootable Windows disk so that you can use it to repair the boot after removing Ubuntu.
You must have a DVD or USB of the installed Windows version.
Don’t worry, you can easily download and create a Windows 10 live USB. So if you have your Windows disk with you, let’s see how to remove Ubuntu from dual boot Windows.
Deleting Linux from dual boot is done in two parts. The first is to delete the partition(s) on which Linux was installed. The second part is to fix the Windows boot loader, as just deleting the Linux partition will result in a Grub rescue error.
Part 1: Deleting Linux partition on Windows
Log into Windows. Press Windows+R and type diskmgmt.msc into the dialog box. This will open the Windows disk management tool.
Since you installed Linux, it’ll be easy for you to recognize the Linux partition by its size. Another hint for identifying the Linux partition is to look for those that don’t have a file system and drive number. Windows partitions are labeled with a drive number, such as C, D, E, etc., and usually use the NTFS or FAT file system.
As you can see, I have three Linux partitions here as I created root, swap and home separately when I installed Ubuntu.
Select the Linux partition(s), right click on them and opt for the Delete Volume option.
It will throw you a warning – just select Yes here.
The deleted partition(s) will now be available as a chunk of free space. You can either extend the existing volume or create a new Windows partition from it. I would suggest that you create a new drive (or volume or partition, whatever you want to call it) as this will be easier if you decide to dual boot Linux with Windows again.
Part 2: Fixing Windows boot loader
Once you’ve deleted the Linux partition, it’s time to fix the Windows boot loader. The pictures here might not be that clear as it’s easier to take screenshots of the login screen in Ubuntu than in Windows. I took them with my phone camera.
Put in the Windows installation disk and restart your computer. Press F10 or F12 at boot time to go into BIOS/UEFI and choose to boot from removable disk.
Choose to repair your computer:
Go for the Troubleshoot option here:
On the troubleshooting page, choose Advanced options:
Look for the command prompt option in here:
In the command line, type the following command to fix the Windows boot loader:
Normally, it works instantly. You don’t even have to wait for it.
Once it’s done, restart your computer and this time boot normally from the hard disk. You should be able to boot into Windows. If you still see a Grub rescue error, try the steps below.
Step 8: If the trick in step 6 didn’t work
If the command in step 6 didn’t work, try Automatic repair from the advanced troubleshooting options.
It will take some time to find the issue and then repair it.
Now if you reboot, you should go into Windows normally without seeing any Grub rescue error thingy.
I hope this guide helped you safely remove Ubuntu from Windows dual boot. Feel free to ask any questions or make a suggestion.
