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
I Installed Kali Linux In My Windows 10 Actually I Dual Booted It But After Some Time I Uninstalled Kali But Now Few Days Ago I Re-Installed It And Now I Am Not Getting Option To Boot Into windows 10 or Kali Linux. Whenever I Open My Pc It directly Boot into Windows While Searching On Internet I found this Command on your sute Which Is --> bcdedit /set {bootmgr} path \EFI\kali\grubx64.efi Actually It Was Unbuntu Nd I Replaced It with Kali . I Runned This Command Into Windows And It Said Opertion Complted successfully.
After That I restared my pc and i am not getting any boot menu i got directly booted into kali linux :( no windows option :( what to do now
Plx Help M3 :(
Thank you so much this is so helpfull.
great! it worked. thanks a bunch for saving my head scratching for more than a week with repairing GRUB. :) :)
Thanks brother, this led me down the right path. For Debian though, the EFI Path is \EFI\debian\grubx64.efi
Thanks
Thank you very much! I was looking for a answer the whole day and finally this worked for me!!! As Miguel pointed out, we just need to change ubuntu for 'debian' at EFI Path to make it work
Many thanks worked well for elementary OS on the new Acer E5-774, clearing secure boot, was not easy as Acer make it difficult to work out activating the greyed out disable option for secure boot, you have to setup password for Bios/UEFI, before you can clear the secure boot settings and then disable, after disabling and booting using the USB drive, the Grub menu became active on normal boot to OS, many thanks for the command line fix.
Tried it. Didn't work on my new HP.
this is a shitty tutorial. after this, you won
t be able to boot your windows even. do not follow
same for me, were you able to fix it man?
this worked for me , thanks
amazing! well done! although I had first to choose the recovery option (linux) and then repair the grub... but anyway this save lot's of time. thank you!
sir, same problem but with linux mint .... what is the solution
The set command specified is not valid.
Run "bcdedit /?" for command line assistance.
The parameter is incorrect.
This is MY OUTPUT help please
After trying this, my windows partition isn't working anymore.. after booting up, the screen says "internal hard disk not found; try to reseat the drive. No bootable devices."
What now? Please help me fix this... My Kali Linux partition is working though.. Reply as soon as possible...
you can't say this solution but it's like semi-solution, try functional key during boot, ( For Dell F12 or others)
try Functional Key during Boot, LIKE ( F12 for dell, may be F10 For HP or F8 old ones ).....
Sir, I had windows 10 Installed in my HP notebook,
I dual booted with RHEL 7.4 Workstation.
Now I can't access my Windows 10 from boot menu, only RHEL.
And I have an evolution copy of RHEL 7.4 installed,
So I can't install anything on it,
Plz tell me what to do.. and how to recover Windows back..
One thing.
I can see windows partitions from linux,
Thank you sir!
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
