so it wants to boot into ubuntu:

just to be sure, you no longer have ubuntu and windows installed?
so that we can remove the entries

No, just Manjaro on this machine. :slight_smile:

ok so lets delete the windows/ubuntu entries:
sudo efibootmgr -b 0001 -B
sudo efibootmgr -b 0002 -B

reboot and see if it helped
if not post output again from:
efibootmgr -v

Hi @brahma ,

Thank you so much.

Just to confirm, please: doing this will not cause any harm or make the machine unbootable?

And, sorry for this . :slight_smile:

no, i dont see why it should mess things up, it removes the ubuntu and windows, since you dont have them anymore, and you should then be able to boot normally …

Hi @brahma,

So, I did the procedure.

And now the system does not boot anymore. :frowning:

It falls always in a Windows like Blue screen mentioning restoring.

And at BIOS, on boot priority order, there are now 3 entries:

  • Windows Boot Manager (ST2000LM007-1R8174)
  • Windows Boot Manager
  • Windows Boot Manager

What can I do now, please?

that should not happened…
are you sure you completely removed windows?
what is this windows partition:?


so do this:

Well, there’s something strange here.

I was able to start Manjaro, but for that I had to enter my Acer’s boot menu (F12). Here I have 3 options:

  • Windows Boot Manager
  • Manjaro
  • Unknown Device

Choosing Manjaro I can perfectly enter the OS. But, why is happening that?

Below is the output of the efibootmgr -v command:

Regarding that partition you mentioned, at GParted I can see it is ntfs, and as label it has only Basi.

Do you think I can run the last procedures you suggested?

this is what i meant with boot options:


the windows is still not deleted… whats the size of the windows partition? are there any files on it?

Ah, ok.

So, that ntfs partition (/dev/sda5) has 1 GB. No files on that, and I don´t use Windows for more than 6 months. In fact, I have uninstalled Windows and also deleted its partition.

I also noticed here a fat32 partition (/dev/sda1) which mount point is /boot/efi .

have no idea what that partition is…
ok, so now change the bootorder, so that manjaro is first:

sudo efibootmgr -o 0003,0000,0001,2001,2002,2003

reboot and see if it boots directly into manjaro

Thanks for your help and kindness.

So, I ran the command and also a efibootmgr -v, which output is correct.

But rebooted and now again the output is as below:

efibootmgr -v

I really don’t understand what is happening here.

so make the windows inactive:

sudo efibootmgr -b 0000 -A

reboot and see if you can boot normally into manjaro

Just tried this, but the command returns an error:

sudo efibootmgr -b 0000 -A
efibootmgr: Boot entry 0 not found
Could not set active state for Boot0000: No such file or directory

running this gives you the same error:

sudo efibootmgr -b 0 -A

Yes, the same.

very strange…
