I have an acer laptop and after dual-booting, it brings me back immediately to windows. When I check the bootloader, Ubuntu is not there. I've also tried using the command

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

But it still doesn't work. So I tried to use the boot-repair tool in the 'Try Ubuntu option' instead of installing it again. It still doesn't work and tells me to post this for reference.


Appreciate any help!

  • Is secure boot enabled? (If it is you should disable it) – itssme Jan 13 '17 at 9:09
  • Isn't it suppose to work even with secure boot enabled? – John Jan 13 '17 at 10:26

I remember getting this error whenever there was some sort of Windows update.

I solved it by booting into Ubuntu live USB, and do:

sudo update-grub

Additionally, you can check out this solution from windows: https://itsfoss.com/no-grub-windows-linux/
