Notebook Boot and Lockup

Hi there.

I have decided to install Linux on my hard drive (the 2TB one instead of the 128GB Solid State drive), and Linux successfully installed on the partition that I made available from the 2TB drive. I used the Linux distribution for a while and it was working successfully, no problems. I wanted to replace the Linux distribution with another one, which installed successfully in the same partitioned space as the first one, but then it couldn't install the Grub Bootloader at the end to complete the installation. I have tried several times to install Linux and the Grub bootloader, but still no success. I decided to remove all partitions and restore my 2TB drive to its original state, but now I am stuck with 2 Linux OS boot managers (UEFI) underneath the original "Windows Boot Manager" on the boot selection screen when I press the "F9 hot key"

It currently looks like this:

-------------------------------------------
Boot Option Menu

OS boot Manager (UEFI) - Windows Boot Manager
OS boot Manager (UEFI) - Linux(1)
OS boot Manager (UEFI) - Linux(2)
Boot From EFI File
-------------------------------------------

Any help to remove those 2 Linux entries would be greatly appreciated, because currently Grub won't install, and there's no way I can reinstall Linux without Grub bootloader. I would most probably be able to reinstall Linux once those entries have been removed and the boot manager menu only has the Windows Boot Manager option left.

Thanks in advance
