I have new information which may help this laptop and many others. Apparently a change in the Logic of the installer may fix this issue for this laptop and many others. I have obtained this information from a friend who develops for EndlessOS. He expolains why EndlessOS installs so well on stubborn systems:
Endless, unlike other distributions, copies their bootloader to the fallback location (EFI/BOOT/bootx64.efi) on the EFI partition. Other distributions don't do that because they don't want to fight with Windows for ownership of this fallback boot loader. And your laptop is one the few bad ones that always boots the fallback entry regardless of what is in the EFI variables. So, here are your options: Install Debian, or install Ubuntu using the alternative installer. When booting the installer, select Advanced options > Expert install. When asked about installation of the boot loader into the removable media path, say Yes. Install any other distribution. Fix up the incomplete installation by booting the installer in rescue mode. All you need to do is to copy grubx64.efi from its original location to EFI/BOOT/bootx64.efi. Or, if Secure Boot is enabled, copy shim.efi to EFI/BOOT/bootx64.efi instead, and also copy grubx64.efi near it. Hopefully this list of md5sums from an Endless 3.5 VM will help. fallback.efi is something Endless-specific that fixes the boot order, but you should not need that. 75238f560aee0c2c1ff8fd8059de162f ./EFI/BOOT/fallback.efi 2a03c6987a88764801ce51e5e4ad3ad8 ./EFI/BOOT/bootia32.efi 7661abbf92a68466a3562ec887365e6a ./EFI/BOOT/bootx64.efi 23f901ffd8afd7d4077d415319acae70 ./EFI/endless/MokManager.efi 6d4a0f0e0d9770450313ab8223c95672 ./EFI/endless/grubx64.efi ead39d2076f31634eef2ac4b2638d1e6 ./EFI/endless/BOOT.CSV 7661abbf92a68466a3562ec887365e6a ./EFI/endless/shim.efi So perhaps a way around this bug is just to change the assumptions that the installer makes when someone decides they want to wipe the drive clean. I would be ok if Installing alongside windows fails. I should add that the alternative installer approach failed.
