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.efiYou 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.
i tried this. it still booted straight to windows 10. :P

Lenovo E570 - Dual boot Windows 10 and Ubuntu 17.04
After Windows automatic update Grub disappeared, only Windows boot available.
I tried the solution of this post but it didn't work.
Simply the fix was to go in BIOS > Security > Secure boot > Disable.
I suspect that secure boot was re-enabled by the automatic Windows update and it was preventing also the use of Linux live from USB.
i tried this. its working fine thanks dude
thanks, it worked fine
thank"s its so help me ,.. thank's thanks to you ,... :D ,.. like this
I did this, and now my computer just shows "reboot and select proper boot device or insert boot media in selected boot device and press key' but doesn't seem to be responding to anything I do. I was not expecting for my computer to get messed up this badly- i can't even use it now. Help?????
same thing happened to me. My windows boot manager is completely messed up and now I can't open windows. Very mad that this one command line messed up my computer so bad. Can anyone fix this?
Yeah, i can fix it. You need the disc or usb bootable windows media (if you have windows 10, use a bootable windows 10 media) Choose Repair your computer after you select the language, time and keyboard method
Select your Windows installation drive (usually C:\)
Click Next
Select Command Prompt in the System Recovery Options box
Write the following command and press Enter:
"bootrec /rebuildbcd" and "bootrec /fixboot"
Reboot and it should wok
Mine is debian but this [bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi] couldn't fix it. You helped only Ubuntu users
yet one more piece of BS foisted as exprtise
Hey Abhishek,
i tired the bcdedit command but no luck. I'm still not getting the grub to select Ubuntu. My windows 10 loads everytime.
I've tried changing secure boot and even legacy boot options but no luck there as well.
I had installed the ubuntu 16.10 from a DVD using legacy boot option enabled as the EFI was not booting from DVD. i believe the ubuntu i had installed is 32 bit one as it was prior installed on a windows 7 32 bit system. but lscpu shows me it is compatible with both 32 and 64 bit and post installation on my new windows 7 laptop i didn't get any errors. so is there anything else i'm missing please let me know
thanks in advance.
I tried all the step exactly but still I don't get the grub it directly starts Windows 10.
I tried legacy boot mode and secured boot disabled but no luck
Is it possible because the Ubuntu 16.10 I've installed along side Windows is a 32bit one?
I'm asking this because I was using this version with my Windows 7 in another 32bit laptop, I had installed the same Ubuntu now on my new 64bit laptop, so should I change the bcdedit command to x32 and try pls let me know..
soooooooooooooooooo much thanks. worked like a charm
I tried this page's guide, boot repair (from live ubuntu usb,) and this https://askubuntu.com/questions/681422/grub-menu-not-showing-with-dual-boot-uefi-mode-installation (with ubuntu live usb)
One, some or all the above may have helped, but what solved it in the end was a couple of settings in BIOS. I turned of Secure Boot and went to the menu BOOT>UEFI Hard Disk Drive BSS Priorities, there I changed the boot loader to GRUB :)
Hi! This fix helped me to run Ubuntu. I just got a problem to boot back to Win10. If I choose it in the Grub menu I get "Windows failed to start. A recent hardware or software change might be the cause.."
Any suggestion how to fix this to be able to choose between those two freely?
Thanks. J.
