Uninstall Grub and use Windows bootloader

I have Windows 8 pre-installed and then installed Grub with Ubuntu. Ubuntu is not my thing so now I want to remove it along with grub. From what I have learned, with UEFI, Grub does not overwrite the windows bootloader in the EFI partition and is stored elsewhere. How would I remove grub and make my PC use the Windows bootloader instead? It should be noted that I created a seperate /boot partition when installing Ubuntu.

For those who have UEFI systems or who deleted the Ubuntu partitions and were left with grub that isn't fixed by the below answer(s), scroll down to see my recently added answer that can be administered from within Windows with no USB or DVD media required.

I think you would solve your problem just using "windows" as your first entry on grub.

This answer is for those with UEFI who have deleted the Ubuntu partitions before removing grub
You will be doing this from Windows 10. No bootable media required.
Where bootrec /fixmbr
, bootsect /nt60
and the Ubuntu live with the boot-repair
suggestions have failed, this has worked for me:
(This answer borrowed verbatim from here)
- Run a
cmd.exe
process with administrator privileges - Run
diskpart
- Type:
list disk
thensel disk X
where X is the drive your boot files reside on - Type
list vol
to see all partitions (volumes) on the disk - Select the EFI volume by typing:
sel vol Y
where Y is theSYSTEM
volume (this is almost always the EFI partition) - For convenience, assign a drive letter by typing:
assign letter=Z:
where Z is a free (unused) drive letter - Type
exit
to leave disk part - While still in the
cmd
prompt, type:Z:
and hit enter, where Z was the drive letter you just created. - Type
dir
to list directories on this mounted EFI partition - If you are in the right place, you should see a directory called
EFI
- Type
cd EFI
and thendir
to list the child directories insideEFI
- Type
rmdir /S ubuntu
to delete the ubuntu boot directory
Assuming you only ever had two operating systems (Win 10 & Ubuntu) you should now be able to boot directly to Windows without hitting the black grub screen.

I installed (rather upgraded win 7 to 10).
Formatted the Ubuntu drive, from windows explorer.
Still after that, GNU Grub was showing the Ubuntu options.
To enable me auto-restarting in Win 10,
- Logged into Win 10
- Press Win+X
- Open Command Prompt (Admin)
c:> bootsect /nt60 <drive name>: /mbr
Thats it.
Hope it helps

Some CISCO Talos annoyware was preventing me from doing this from within my OS, but as of Windows 10 you no longer need an install disk to do this. I have just done this operation without one; all you need to do is log out so you're on the log in screen, then you start holding down Shift, and press the power icon in the bottom right, then click Restart, now let go of Shift. This will open the same menu as the repair disk. You just have to go to Troubleshoot > Advanced options > Command Line and runbootsect /nt60 c: /mbr
. Grub will be gone in an instant.

Does not appear to work for me. Grub appears until I press exit. Updated NTFS filesystem bootcode. The update may be unreliable since the volume could not be locked during the update: Access is denied. ??PhysicalDrive0 Bootcode is only updated on MBR partitioned disks. A different partitioning scheme is used on this disk. Bootcode was successfully updated on all targeted volumes. PS C:WINDOWSsystem32>

What does the /mbr do? I looked for documentation on bootsect, and I couldn't find anything about /mbr.

You can restore the Windows bootloader with a Windows 8/8.1 DVD. These instructions are inspired by Manindra Mehra's answer, but I expanded it with full working details (verified with a Windows 8.1 DVD).
Put the DVD in your optical drive and boot from it.
Press a key when it displays
Press any key to start from CD or DVD
.Select your language etc. and click
Next
.Click
Repair your computer
.Click
Troubleshoot
.Click
Advanced Options
.Click
Command Prompt
.In the command prompt window, type
bootrec /fixmbr
Click the red
X
to close the command prompt.Click
Turn off your PC
.Turn the PC back on and it should boot directly into Windows.
This leaves the Ubuntu partition on your hard drive or SSD. To remove it:
Hit
Windows
+X
and selectDisk Management
.Find the Ubuntu partition. It will probably be a large partition without a drive letter.
Be sure you have the correct partition!
Right-click the partition and delete or reformat it with a Windows filesystem.

To do so you will need a windows installation cd/dvd
- put it in your optical drive and boot from it
- on the installation screen where it asks you to install windows, click on Repair Your Computer on the lower left corner of your screen
- Now go to command prompt (It probably will show a window saying "Trying to repair windows automatically", close it) and type
BootRec.exe /fixmbr
- after it finishes GRUB is gone and you can now boot into windows directly
- you have an Ubuntu partition left in your computer, that doesn't show in "My Computer", to access that, right click on "My Computer" and Select "Manage" and go to "Disk Management"
- Select the Ubuntu partition and format it to a file system that windows can use.
For completeness, also remove ubuntu from the efi boot menu. I think this should be added as step 7.

Please fix step 3 by explaining how to go to command prompt. Michael Geary's answer is more complete. This answer led me to reset my PC unnecessarily once because I didn't know how to go to command prompt.

With UEFI you have both a Windows folder & an Ubuntu folder in the efi partition. the UEFI reads the efi entries and adds them to its own NVRAM to remember them. You have to remove ubuntu folder from efi partition first or UEFI will re-add it. Then you have to remove UEFI entry from UEFI.
You should have these folders in the efi partition. Delete only the ubuntu folder. Live installer should show folders. And if only Windows you have to mount from inside Windows the efi partition as it is not normally mounted.
/EFI/Boot
/EFI/Microsoft
/EFI/ubuntu
You should not have to install Ubuntu but can use live installer DVD or flash drive. Some UEFI systems may let you do the UEFI edit from UEFI menu.
from liveDVD or flash and use efibootmgr
sudo efibootmgr -v
The "-v" option displays all the entries so you can confirm you're deleting the right one, and then you use the combination of "-b ####" (to specify the entry) and "-B" (to delete it). Examples #5 is delete:
http://linux.dell.com/cgi-bin/gitweb/gitweb.cgi?p=efibootmgr.git;a=blob_plain;f=README;hb=HEAD
http://software.intel.com/en-us/articles/efi-shells-and-scripting/
This was helpful in directing what I needed to do. I could delete the ubuntu partition in Windows using informaition from here: superuser.com/questions/662823/…

You can also use a USB memory stick for this job. It takes three applications: Unetbootin, FreeDOS and Testdisk for DOS.
- First download Unetbootin and use it to make a bootable USB memory stick. Choose Freedos when prompted for a distribution to install on it.
- Download Testdisk for DOS (don't pick the beta, but pick the stable version).
- Unzip the files testdisk.exe and CWSDPMI.exe, and put them on the bootable memory stick (not in a folder, just straight on it).
- Boot your computer from the memory stick. At the Default window, simply press Enter.
- Now FreeDOS is being launched. Choose:
FreeDOS Safe Mode (don't load any drivers)
and Press Enter. - Then type:
C:
and Press Enter. - Now type:
testdisk
and Press Enter. - Select
[No Log]
and Press Enter. - Select the hard drive concerned: usually the second option (the first option is the memory stick itself) and Press Enter.
- Select
[Intel]
and Press Enter - Select
[MBR Code]
and press Enter. When prompted, typey
(yes) and press Enter again.
Now you're done! Reboot your computer normally. Your computer should boot up Windows now.

If All Else Fails!
The guy above me's method does not work on newer EFI computers. I solved the problem. Here is how I did it. WARNING, you have to reinstall Linux / grub first!
Steps: (this is if nothing else works and takes a long time)
1: Reinstall Ubuntu / Linux mint (this is just so you can use GRUB to boot into Windows).
1.5: Restart and boot into windows (if you can't boot to Windows, then live boot from the CD or USB and run the following in a console:
If you have a windows repair disk you can select the UEFI firmware option and load Windows from there (to avoid reinstalling Linux)
Boot repair (if needed right now)
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && (boot-repair &)
1g: Select recommended repair and follow the on screen instructions.
2g: After your done, reboot. You should see the grub menu, even though you can boot to Windows from here, this is not what we want yet... But find the option that boots into Windows.
2: Once your booted into Windows, run your disk partition editor and delete All partitions related to Linux / grub. Especially make sure the small grub partition is removed. Reboot
2.5: Make sure the windows loader is the first selected boot device. (most likely is). Disable the Ubuntu option. Continue boot.
3: If you've done everything right up to this point you should see (depending on your computer) your splash screen for a second and then it will turn into an error screen saying that there was an error with the boot. ("Winload.exe is missing or corrupted" most likly).
3.5: Don't be alarmed (I was). The next step will restore your original bootloader.
4: Restart and boot to your Linux CD or USB.
5: Once booted, run boot repair commands from above again. This time when running it. It will act differently, there is no grub bootloader detected to reinstall and should run faster than before.
6: Once complete, restart.
7: Enjoy your GRUB free system!
This worked for me when nothing else did, I ran bootrec.exe. Nothing worked. This saved my computers life. Hope it saves yours!

No CD's, USB's, DVD's. No long tutorials.
On UEFI all you have to do is:
Place Windows boot entry in NVRAM as first.
How to do this - several solutions.
Easiest solution is to use firmware functionality and reorder NVRAM boot entries.

For system with GPT partition table, the method provided by @Ganesh Kondal won't work. Using bootsect /nt60 C: /mbr
will show that it worked while it really doesn't. Using bootrec /fixmbr
will lead to error that "the system cannot find the file specified". If any of the above situation applies, do the following (Using Windows 10 as an example):
- at log in prompt, hold shift, click on power button, choose restart, let go of shift
- choose troubleshoot -> advanced options -> command line
- at command line, type in
bcdboot <drive name>:windows
for more detailed information, also look at this webpage:https://www.tenforums.com/general-support/74226-bootmgr-error-cant-find-fix.html

What worked for me is:
- Boot to Windows
- Win + X
- Command Prompt (as admin)
bcdedit /set {bootmgr} path EFIMicrosoftBootbootmgfw.efi
- Reboot

What does the /mbr do? I looked for documentation on bootsect, and I couldn't find anything about /mbr.

I installed (rather upgraded win 7 to 10).
Formatted the Ubuntu drive, from windows explorer.
Still after that, GNU Grub was showing the Ubuntu options.
To enable me auto-restarting in Win 10,
- Logged into Win 10
- Press Win+X
- Open Command Prompt (Admin)
c:> bootsect /nt60 <drive name>: /mbr
Thats it.
Hope it helps

Some CISCO Talos annoyware was preventing me from doing this from within my OS, but as of Windows 10 you no longer need an install disk to do this. I have just done this operation without one; all you need to do is log out so you're on the log in screen, then you start holding down Shift, and press the power icon in the bottom right, then click Restart, now let go of Shift. This will open the same menu as the repair disk. You just have to go to Troubleshoot > Advanced options > Command Line and runbootsect /nt60 c: /mbr
. Grub will be gone in an instant.

Does not appear to work for me. Grub appears until I press exit. Updated NTFS filesystem bootcode. The update may be unreliable since the volume could not be locked during the update: Access is denied. ??PhysicalDrive0 Bootcode is only updated on MBR partitioned disks. A different partitioning scheme is used on this disk. Bootcode was successfully updated on all targeted volumes. PS C:WINDOWSsystem32>

You can restore the Windows bootloader with a Windows 8/8.1 DVD. These instructions are inspired by Manindra Mehra's answer, but I expanded it with full working details (verified with a Windows 8.1 DVD).
Put the DVD in your optical drive and boot from it.
Press a key when it displays
Press any key to start from CD or DVD
.Select your language etc. and click
Next
.Click
Repair your computer
.Click
Troubleshoot
.Click
Advanced Options
.Click
Command Prompt
.In the command prompt window, type
bootrec /fixmbr
Click the red
X
to close the command prompt.Click
Turn off your PC
.Turn the PC back on and it should boot directly into Windows.
This leaves the Ubuntu partition on your hard drive or SSD. To remove it:
Hit
Windows
+X
and selectDisk Management
.Find the Ubuntu partition. It will probably be a large partition without a drive letter.
Be sure you have the correct partition!
Right-click the partition and delete or reformat it with a Windows filesystem.

To do so you will need a windows installation cd/dvd
- put it in your optical drive and boot from it
- on the installation screen where it asks you to install windows, click on Repair Your Computer on the lower left corner of your screen
- Now go to command prompt (It probably will show a window saying "Trying to repair windows automatically", close it) and type
BootRec.exe /fixmbr
- after it finishes GRUB is gone and you can now boot into windows directly
- you have an Ubuntu partition left in your computer, that doesn't show in "My Computer", to access that, right click on "My Computer" and Select "Manage" and go to "Disk Management"
- Select the Ubuntu partition and format it to a file system that windows can use.
For completeness, also remove ubuntu from the efi boot menu. I think this should be added as step 7.

Please fix step 3 by explaining how to go to command prompt. Michael Geary's answer is more complete. This answer led me to reset my PC unnecessarily once because I didn't know how to go to command prompt.

With UEFI you have both a Windows folder & an Ubuntu folder in the efi partition. the UEFI reads the efi entries and adds them to its own NVRAM to remember them. You have to remove ubuntu folder from efi partition first or UEFI will re-add it. Then you have to remove UEFI entry from UEFI.
You should have these folders in the efi partition. Delete only the ubuntu folder. Live installer should show folders. And if only Windows you have to mount from inside Windows the efi partition as it is not normally mounted.
/EFI/Boot
/EFI/Microsoft
/EFI/ubuntu
You should not have to install Ubuntu but can use live installer DVD or flash drive. Some UEFI systems may let you do the UEFI edit from UEFI menu.
from liveDVD or flash and use efibootmgr
sudo efibootmgr -v
The "-v" option displays all the entries so you can confirm you're deleting the right one, and then you use the combination of "-b ####" (to specify the entry) and "-B" (to delete it). Examples #5 is delete:
http://linux.dell.com/cgi-bin/gitweb/gitweb.cgi?p=efibootmgr.git;a=blob_plain;f=README;hb=HEAD
http://software.intel.com/en-us/articles/efi-shells-and-scripting/
This was helpful in directing what I needed to do. I could delete the ubuntu partition in Windows using informaition from here: superuser.com/questions/662823/…

You can also use a USB memory stick for this job. It takes three applications: Unetbootin, FreeDOS and Testdisk for DOS.
- First download Unetbootin and use it to make a bootable USB memory stick. Choose Freedos when prompted for a distribution to install on it.
- Download Testdisk for DOS (don't pick the beta, but pick the stable version).
- Unzip the files testdisk.exe and CWSDPMI.exe, and put them on the bootable memory stick (not in a folder, just straight on it).
- Boot your computer from the memory stick. At the Default window, simply press Enter.
- Now FreeDOS is being launched. Choose:
FreeDOS Safe Mode (don't load any drivers)
and Press Enter. - Then type:
C:
and Press Enter. - Now type:
testdisk
and Press Enter. - Select
[No Log]
and Press Enter. - Select the hard drive concerned: usually the second option (the first option is the memory stick itself) and Press Enter.
- Select
[Intel]
and Press Enter - Select
[MBR Code]
and press Enter. When prompted, typey
(yes) and press Enter again.
Now you're done! Reboot your computer normally. Your computer should boot up Windows now.

and Press Enter. - Select the hard drive concerned: usually the second option (the first option is the memory stick itself) and Press Enter.
- Select
[Intel]
and Press Enter - Select
[MBR Code]
and press Enter. When prompted, typey
(yes) and press Enter again.
Now you're done! Reboot your computer normally. Your computer should boot up Windows now.
You can also use a USB memory stick for this job. It takes three applications: Unetbootin, FreeDOS and Testdisk for DOS.
- First download Unetbootin and use it to make a bootable USB memory stick. Choose Freedos when prompted for a distribution to install on it.
- Download Testdisk for DOS (don't pick the beta, but pick the stable version).
- Unzip the files testdisk.exe and CWSDPMI.exe, and put them on the bootable memory stick (not in a folder, just straight on it).
- Boot your computer from the memory stick. At the Default window, simply press Enter.
- Now FreeDOS is being launched. Choose:
FreeDOS Safe Mode (don't load any drivers)
and Press Enter. - Then type:
C:
and Press Enter. - Now type:
testdisk
and Press Enter. - Select
[No Log]
and Press Enter. - Select the hard drive concerned: usually the second option (the first option is the memory stick itself) and Press Enter.
- Select
[Intel]
and Press Enter - Select
[MBR Code]
and press Enter. When prompted, typey
(yes) and press Enter again.
Now you're done! Reboot your computer normally. Your computer should boot up Windows now.

If All Else Fails!
The guy above me's method does not work on newer EFI computers. I solved the problem. Here is how I did it. WARNING, you have to reinstall Linux / grub first!
Steps: (this is if nothing else works and takes a long time)
1: Reinstall Ubuntu / Linux mint (this is just so you can use GRUB to boot into Windows).
1.5: Restart and boot into windows (if you can't boot to Windows, then live boot from the CD or USB and run the following in a console:
If you have a windows repair disk you can select the UEFI firmware option and load Windows from there (to avoid reinstalling Linux)
Boot repair (if needed right now)
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && (boot-repair &)
1g: Select recommended repair and follow the on screen instructions.
2g: After your done, reboot. You should see the grub menu, even though you can boot to Windows from here, this is not what we want yet... But find the option that boots into Windows.
2: Once your booted into Windows, run your disk partition editor and delete All partitions related to Linux / grub. Especially make sure the small grub partition is removed. Reboot
2.5: Make sure the windows loader is the first selected boot device. (most likely is). Disable the Ubuntu option. Continue boot.
3: If you've done everything right up to this point you should see (depending on your computer) your splash screen for a second and then it will turn into an error screen saying that there was an error with the boot. ("Winload.exe is missing or corrupted" most likly).
3.5: Don't be alarmed (I was). The next step will restore your original bootloader.
4: Restart and boot to your Linux CD or USB.
5: Once booted, run boot repair commands from above again. This time when running it. It will act differently, there is no grub bootloader detected to reinstall and should run faster than before.
6: Once complete, restart.
7: Enjoy your GRUB free system!
This worked for me when nothing else did, I ran bootrec.exe. Nothing worked. This saved my computers life. Hope it saves yours!

No CD's, USB's, DVD's. No long tutorials.
On UEFI all you have to do is:
Place Windows boot entry in NVRAM as first.
How to do this - several solutions.
Easiest solution is to use firmware functionality and reorder NVRAM boot entries.

For system with GPT partition table, the method provided by @Ganesh Kondal won't work. Using bootsect /nt60 C: /mbr
will show that it worked while it really doesn't. Using bootrec /fixmbr
will lead to error that "the system cannot find the file specified". If any of the above situation applies, do the following (Using Windows 10 as an example):
- at log in prompt, hold shift, click on power button, choose restart, let go of shift
- choose troubleshoot -> advanced options -> command line
- at command line, type in
bcdboot <drive name>:windows
for more detailed information, also look at this webpage:https://www.tenforums.com/general-support/74226-bootmgr-error-cant-find-fix.html

What worked for me is:
- Boot to Windows
- Win + X
- Command Prompt (as admin)
bcdedit /set {bootmgr} path EFIMicrosoftBootbootmgfw.efi
- Reboot

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?
For those who have UEFI systems or who deleted the Ubuntu partitions and were left with grub that isn't fixed by the below answer(s), scroll down to see my recently added answer that can be administered from within Windows with no USB or DVD media required.

I think you would solve your problem just using "windows" as your first entry on grub.
