bkpbootx64.efi is not a standard windows boot file. Have you modified your computer in any way?– TheKBCommented May 28, 2016 at 14:06

The bkpbootx64.efi is a backup regularly created by Boot-Repair. With Windows the bootx64.efi is just really a copy of Windows bootmgfw.efi. And bootx64.efi is a fallback or hard drive boot entry in UEFI.
But Boot-Repair with its 'Use the standard EFI file` in advanced options creates the bkpbootx64.efi and makes bootx64.efi a copy of shimx64.efi so fallback or hard drive boot entry in UEFI really boots grub not Windows.
About the only way to tell which is which is by checking file size or what actually boots. If Boot-Repair created 25_custom for all the HP entries you probably can delete most or all of them.
Edit 25_custom entries created by Boot-Repair:
sudo cp -a /etc/grub.d/25_custom /etc/grub.d/bkp25_custom
turn off execute bit or it will run backup also
sudo chmod a-x /etc/grub.d/bkp25_custom
sudo nano /etc/grub.d/25_custom
Then do:
sudo update-grub
