PC boots into Windows despite setting up dual boot


I have installed manjaro deepin as a dual boot with windows 10. However, when i boot up my PC it goes straight to Windows 10 instead of showing a grub menu.
How can I fix this? Thank you.

Please help ;-;


Did you install Manjaro on same drive as Windows or on the second drive? With an UEFI install you will need to create a FAT32 partition and mount it as EFI.

My advice is to use the other drive for Linux and install grub on that one. When you want to boot in Linux use your motherboard’s boot menu to select with drive to from.


You did not do the UEFI commands in the link.
Never mind, I’ll write it down again for you. here.

Boot into installed Manjaro.
At terminal, do the following.
And provide the output together with your input command.
First check at terminal that manjaro is in sda with command

findmnt /

That should give output of
/ /dev/sda7 ext2 rw,noatime,xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Note it says “/dev/sda7”
If it says “/dev/sdb7”, change all “sda” below to “sdb”


sudo parted /dev/sda set 9 boot on
sudo grub-install
sudo update-grub
sudo cp /boot/grub/x86_64-efi/core.efi /boot/efi/EFI/boot/bootx64.efi
sudo efibootmgr -c -d /dev/sda -p 9 -L "manjaro" -l "\EFI\Manjaro\grubx64.efi"


I only have one drive, and I used the free space to create partitions for Manjaro on.
In one attempt I created a FAT32 partition and mounted it as EFI, no success.
In another attempt I used the already-existing FAT32 partition on my hard drive and made that EFI, again, no success.


Decide which esp to use and follow @gohlip 's advice to set the boot entry. Adjust the proposed commands appropriately depending your chosen esp partition.

not just a statement of “I followed the tutorial”. This can be interpreted in many different ways.


The output when typing findmnt / is:

[sam@sam-pc ~]$ findmnt /
/      /dev/sda7 ext4   rw,noatime,data=ordered

When I typed

sudo parted /dev/sda set 9 boot on

terminal said I may need to update /etc/fstab.
Should I continue with your directions or update that? If so, how would I update it?


which is probably not needed in your case. You could inspect it if the system partitions UUID match to what they should. If you don’t know what to look, you probably need some more reading, so you can master your system. Or post your fstab to get an advice.
I think you can proceed with the rest of the advice for now… :face_with_head_bandage:


Ok, so I did everything in your directions, here are the outputs for those last 4 inputs:

Is there anything else I have to do in order to have the option to boot into manjaro without going straight to windows10?

I’ll try rebooting now to see if it works, I will update in a bit.


Still boots straight into Windows 10.
I’m not sure what I should tell you guys to help with troubleshooting, so I’m completely lost at this point, I’m sorry :frowning:


I think I’m just going to leave this problem be and just deal with the hassle of using f9 and manually navigate to manjaro os. Thanks for all your help, guys.


So now ‘manjaro’ is in the efibootentry and is first in bootorder.
Also you can boot manjaro by using F9.
That’s a big improvement.

Your computer is HP Pavillion and HP’s uefi firmware implementation is a bit flaky.
If you can update the bios firmware, it will be good.
Otherwise, see if the following 2 links below can help you get ‘manjaro’ entry into the bios so you don’t have to use F9 each time you want to boot Manjaro.

Good luck.


Last reply, sorry, BUT I DID IT. I FREAKING DID IT! Here’s the solution!

  1. Boot into windows
  2. Open cmd as administrator
  3. Enter bcdedit /set "{bootmgr}" path \EFI\manjaro\shimx64.efi
  4. (Optional). Enter bcdedit /set "{bootmgr}" description "Manjaro"
    That simply makes it easier to identify.
    My savior post which originally had this solution.


I’m not Likely to get a HP Laptop but if I do this will be helpful.
