Windows 10 break grub every time I boot into it


Since my last windows update, every time I boot into windows, grub is removed :’(

To get my grub and manjaro back, I have to do the things in this video every time: Manjaro: recover GRUB after a Windows Update - YouTube

Does someone know how can I prevent windows from breaking grub again?

I hope someone can help me with that :slight_smile:


Use a EFI Partition for each OS and nothing will break. Grub can find all EFI Partitions.


Yeah. Remove it.

Sorry. Not sorry.
Just couldn’t help myself


@megavolt method is the best, but have you tried the following?

  1. From Windows, run cmd.exe as Administrator
  2. Enter: bcdedit /set {bootmgr} path \EFI\manjaro\grubx64.efi
  3. Restart

I haven’t had any issues with Windows updates affecting my GRUB using this method after my initial install. Hopefully it helps you.

I wish I could :slight_smile:

Thank you for your answer, I have written the exact command like you said

Thank you very much! It worker!!!

I remember writting a command like that in the past, maybe the windows update had break it.

Thank you for your answer.

It looks quite complicated x)

@summrum method had worked for now

I’m really pleased it has solved your issue. I don’t think it’s as sure-fire a method as separate EFI partitions as @megavolt suggested, so if the problem reappears re-partitioning may be the best solution.
