Try this, and reboot:

sudo cp -v /mnt/sda11/EFI/Manjaro/grubx64.efi /mnt/sda2/EFI/manjaro/

43

It booted into the windows directly

44

Hold down the key that lets you select boot devices when the computer is booting up. No entry for “manjaro” still?

45

EDIT: What was the output of:

sudo cp -v /mnt/sda11/EFI/Manjaro/grubx64.efi /mnt/sda2/EFI/manjaro/

46

It was this
/mnt/sda11/EFI/Manjaro/grubx64.efi - - > /mnt/sda2/EFI/manjaro/

And manjaro entry is still not showing

47

Really running out of ideas here, and the partition layout seems complex for a dual-boot setup. :worried:

Just to rule something out, can you post the entire output of:

sudo smartctl -a /dev/sda

You can erase/hide the drive’s serial number before pasting it in here.

48

Prior to copying the .efi file,that made sense, since your esp partition (/dev/sda2) did not even have grubx64.efi. But it’s weird that pausing the boot process still does not list an extra entry.

A real concern is that grub-install cannot detect the file system of your root partition.

49

What is the ext4 file system under /dev/sda9 by the way? It’s not a separate boot partition?

50 
sudo smartctl -a /dev/sda                                        ✔

sda9 is an empty partition, its nothing in there

52

Something’s really up.

First off, /dev/sda11 shouldn’t even exist. It’s an extra FAT32 partition that is not flagged as the “esp”, which means your system does not scan it for EFI boot files when you power on.

Secondly, /dev/sda2 is FAT32 partition flagged as “esp”, which is where you get the Windows boot entry when you pause the boot process. (It happens to be your default EFI boot selection.)

For some reason, the manjaro folder under sda2’s EFI directory was empty.

But all of this should be fixed and at least restore a “manjaro” EFI boot entry when you try to re-install Grub from a live chroot session. (The fact that it boots directly into Windows can always be fixed from within your system/BIOS setup. The real problem is you can’t even override to boot into Manjaro’s Grub menu, since there is no “manjaro” EFI boot entry being detected.)

53

so does that mean i am screwed :sob:

54

This technically should have worked, only changing sda11 to sda2, and leaving the rest the same.

sudo su
mount /dev/sda10 /mnt
mount /dev/sda11 /mnt/boot/efi
cd /mnt
mount -t proc proc /mnt/proc
mount -t sysfs sys /mnt/sys
mount -o bind /dev /mnt/dev
mount -t devpts pts /mnt/dev/pts
chroot /mnt
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
update-grub
exit
exit
reboot

I’m wondering why it failed.

55

You were using the latest ISO version of Manjaro to make that live USB?

56

no it was not latest…it was December 2020 ISO

and i am using ventoy…for multi iso

57

Do your steps using the latest.

Grub has been updated very recently.

Keep in mind not to use sda11, use only sda2 from now on.

58

okay , i think this will take time as my download speed is not that high…i may revert back tomorrow

59

Please do update us on how this works! :slightly_smiling_face:
