Reinstall refind bootloader.

Pre installation
You need to ensure the EFI System Partition (ESP) is mounted when reinstalling rEFInd. The installation process requires access to the ESP to copy rEFInd files to the appropriate location. Here's how to proceed.

sudo mkdir -p /boot/efi
sudo mount /dev/sda1 /boot/efi

Remove old entries

for i in $(efibootmgr | grep '^Boot000' | awk '{print $1}' | sed 's/Boot//;s/\*//'); do
  sudo efibootmgr -b "$i" -B
done

**

The installation**

Steps to Mount ESP and Reinstall rEFInd

1. Verify the Mount: Check that the ESP is properly mounted:

    ls /boot/efi
   

   You should see directories such as EFI.

2. Reinstall rEFInd: Run the installation command:

    sudo refind-install
   

3. Check for Success: Confirm the files are correctly copied into the ESP (e.g., /boot/efi/EFI/refind):

    ls /boot/efi/EFI/refind
   

4. Set Boot Entry: If necessary, recreate the boot entry:

    sudo efibootmgr -c -d /dev/sda -p 1 -L "rEFInd" -l "\EFI\refind\refind_x64.efi"
   

5. Set Boot Order: Update the boot order to prioritize rEFInd:

    sudo efibootmgr -o 0000
   

6. Unmount the ESP (Optional): If you do not need the ESP mounted for other tasks:

    sudo umount /boot/efi
   

7. Reboot: Reboot to confirm rEFInd is working:

    sudo reboot
