A strange "GRUB>" prompt at boot

Hi @Arrababiski ,

Thanks once again.

So, I ran the procedures, but don’t know if I did something wrong. Well, because I obtained similar results.

Take a look at the below screenshot, please:

And again sorry for the disturbance and my dumb questions. :slight_smile:

It seems to me you have an EFI system and I know little about this configuration. Here you have more info to continue looking for information, tells us what you discover and let’s hope somebody else can help to find a solution:

No need to apologize, I’m glad to help in any way I can.

@Arrababiski ,

Thank you very much. Yeah, I have EFI here. I’ll read the suggested article and look for more informations, trying to solve this little issue.

This amazing community is really great!

Since I left Kubuntu I can only thank all the Manjaro community and team. Not only we have a great distro, we also have a wonderful support, with very kind and helpful people, like you. :slight_smile:

Moreover, I am really very well impressed by how Manjaro fantastically detected all my hardware with minimum efforts from my part. Even the Nvidia drivers (which caused several problems on Kubuntu including a broken system) were perfectly and automatically installed, and I am already running some games, including severam with Valve’s Proton.

you still have this windows partition:


i would try reinstalling grub, boot into manjaro live usb, open terminal and chroot with:
manjaro-chroot -a
reinstall it:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck

update it:
mkinitcpio -P && update-grub
if there are no errors exit chroot:
exit
reboot and see if it helped

Hi @brahma ,

Thank you very much.

Sorry for asking this (I am a bit afraid now since the entire system is working and there’s only that “little annoyance” when everything is booting).

Doing the above procedure is there some risk the system becomes unbootable or something similar?

P.S.: I also noticedt there’s a /boot/efi partition (sda1). May this be the correct one?

no nothing will break… but before you do that post also output from:
efibootmgr -v

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
