GRUB dual boot problem in windows

Upgrading windows is not an easy task for dual boot computers. After this process, many things in the PC is change. In this article, we will talk about the GRUB problem for Dual boot users.

 

What is GRUB: The GRUB (Grand Unified Bootloader) is a bootloader available from the GNU project. A bootloader is very important as it is impossible to start an operating system without it. It is the first program that starts when the program is switched on. The bootloader transfers the control to the operating system kernel.

 

If you too are unable to boot into Grub and you’re just rebooting Windows 10 repeatedly, here’s the simple solution that worked for me.

 

Fix Dual Boot system booting straight to Windows

Though I’m referring to Windows 10, the steps are equally valid for Windows 8 and 8.1. Similarly, I’m using Ubuntu in dual boot here, but the trick applies to all other Linux distributions such as Linux Mint, etc.

 

Step 1

In Windows go to the menu.

 

Step 2

Search for Command Prompt, right-click on it to run it as administrator.

 

Step 3

This is strictly for Ubuntu. Other distributions might have some other folder name.

In here, copy and paste the command below:

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

You don’t need to enter a password or anything like that. The command should run just fine given that your account has admin rights.

 

Step 4

Restart and you’ll be welcomed by the familiar Grub screen. I hope this quick tutorial helped you fix the Grub issue.

Again getting any problem?

If the above method didn’t change anything, you can reverse it using the command below:

bcdedit /deletevalue {bootmgr} path \EFI\ubuntu\grubx64.efi

 

Even if the above command didn’t work, try the one below to set the boot back to Windows.

bcdedit /set {bootmgr} path \EFI\Microsoft\Boot\bootmgfw.efi
