After reinstalling Windows 10 on dual boot with Manjaro, Manraro won't boot''

Support

I tried several answers to similar question like reinstalling GRUB.
I use Live CD and manjaro-chroot -a.
I’m not well experienced with the technical side of Linux.

[manjaro /]# update-grub

You need to reinstall grub not just update it with update-grub.

  • Use Live CD and manjaro-chroot -a like before
  • Reinstall grub with:
    # grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
  • Update the grub configuration:
    # grub-mkconfig -o /boot/grub/grub.cfg
  • Exit chroot
    # exit
  • Shut down, remove Live CD and reboot.

GRUB/Restore the GRUB Bootloader - Manjaro .

Thank you for your reply.
Trying to reinstall grub gives this error:

[manjaro /]# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
Installing for x86_64-efi platform.
grub-install: error: /boot/efi doesn't look like an EFI partition.

This doesn’t help directly with Grub. However, you might consider installing REFIND bootloader to a GPT-formatted USB/Thumb drive. Booting from REFIND should discover all bootable EFI instances, and even allow you to bypass Grub, and boot Windows or Manjaro directly.

When finally logged into your system you can more comfortably investigate the issues you’re experiencing. You could also install REFIND to your main EFI partition - It’s installable from the AUR, I seem to remember. You could remove REFIND later once your Grub issues are solved or keep using it, as I do.

Directions for installing REFIND to a USB are outside the scope of this suggestion, but Google can be your friend, along with helpful forum members.

Best of luck.

you have 3 dead kernels:

/boot/vmlinuz-5.16-x86_64
/boot/vmlinuz-5.9-x86_64
/boot/vmlinuz-5.8-x86_64

they need to be removed…

since its a reinstall, is fast startup disabled in windows?
also check in bios/uefi if fast boot is disabled - you may not have this option…
is windows on the same hard disk?

Besides reinstalling grub as a third step, as said above you should disable fast boot in windows secondly.
But firstly, open the bios and check that secure boot is off, the system is in uefi mode and the disks access is in ahci mode and not raid.

Thanks for the replies.
I opted for the meantime to install Manjaro on a new disk.
Manjaro worked until now and whenever there was a problem I found the solution.
For now I can’t find the solution.
The lesson is -
On a dual boot system together with Windows, if you have to reinstall Windows, make sure that your Linux device is disconnected because Windows can corrupt your Linux boot files.

Even that is not a guarantee. Depends on how the uefi makes the boot list. If it is static win can still ovewrite it. Some uefis seem to generate the list dynamically according to what they see on the disk and in that case it will automatically add it to the menu after you connect the disk again. It depends.
