Fix Grub Not Showing For Windows 10 Linux Dual Boot

No grub in dual boot with Linux

So, finally I upgraded Windows 8.1 to Windows 10 last night. Since, I dual boot Windows 8.1 with Ubuntu, I was expecting to see the Grub menu at the boot so that I could choose the operating system of my choice. But the upgrade to Windows 10 from Windows 8.1 messed up the settings and it never showed Grub menu. It just kept booting into Windows 10 at each start up.

Frustrating, isn’t it? It seemed like as if there is no way to access Ubuntu at all. No! the Ubuntu install on the other partition was fine. It was just the UEFI settings that were different in the boot manager. I verified everything by accessing UEFI firmware settings in Windows 10.

If you too are unable to boot into Grub and rebooting Windows 10 repeatedly, I am going to present you the simple solution that worked for me.

Fix no Grub menu in Windows UEFI and Linux dual boot

Though I am saying Windows 10, the steps are equally valid for Windows 8 and 8.1. Similarly, I am using Ubuntu in dual boot here but the trick applies to all other Linux OSes.

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

In here, copy 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. The screen will look something like this:

Step 4

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

Note: If you see a “no boot found” error, you can try this or this solution.

    • No, it’s not retarded.

      Once you’ve booted into Linxu, open a terminal and type…

      sudo update-grub

      This will run Linux’s bootloader which will find Windows. Next time you start your machine, you’ll get a menu where you can pick which operating system you want to boot into.
