blackMORE Ops Learn one trick a day ….
My Razer 2016 laptop had Windows 10, Kali and Ubuntu installed but after a Windows update Linux partitions became inaccessible. I removed both Kali and Ubuntu partitions including SWAP but GRUB was till there. I needed to remove GRUB safely without breaking anything else and the following method on how to remove GRUB bootloader from Windows 10 worked for me. It also works on Windows 7. I’ve used it so far 2/3 times since last year on my laptop running Windows 10 multiple times, never failed. I have Secure boot disabled and I am using Legacy boot on BIOS.
Remove GRUB bootloader from Windows
Follow steps below to remove GRUB from Windows 10.
Step 1(optional): Use diskpart to clean disk
Format your Linux partition using Windows disk management tool. Then you can increase the disk size on your primary partition (i.e. C:) to claim that space. If you’re doing this step, it’s safe to do a restart after you’ve done that.
Step 2: Run Administrator Command Prompt
On Windows 10, Windows 8.1 and Windows 7 search for command and simply right-click Command Prompt shortcut from the search results and select Run as administrator. Don’t use Powershell as PS doesn’t work for few commands.
Step 3: Fix MBR bootsector from Windows 10
Simply type in the following command to remove GRUB bootloader from bootsector on MBR and revert back to Windows bootloader. In Command Prompt (Administrator)
C:\> bootsect /nt60 <drive name>: /mbr
If your drive is C:\ this command will be
C:\> bootsect /nt60 C: /mbr
Thats it. GRUB should be gone from MBR, restart and confirm.
Did not work, friend. I’m never using Ubuntu on anything again.
It’s worked thanks
Worked for Me!!!
Thank you it worked!, Tried every possible way to repair grub/grub rescue and didn’t work. This worked.
Great, it worked for me.

boom! it worked, but be sure to use an “admin” command prompt. type “cmd” in cortana, then hit ctrl-shift-enter to pull it up
Thanks, bro. You saved my day. 100% work.
it works tanks
what is the ‘nt60’?
Thanks a ton, that worked perfectly (I was at the “grub rescue” prompt and was getting nervous!)
not worked on my Acer e15
Just commenting to say that this worked perfectly for me! Ubuntu’s partition was deleted and then I used this command and it worked just as expected.
Great….after lot of searches and almost tired of other methods this simple trick done the work…thank you very much
This is only for systems still on MBR. The world has moved forward you know, people are more likely be on GPT with UEFI. Can you explain how to do it on GPT disks?
