Ubuntu 16.04 boots fine on my UEFI pc with secure boot turned ON
Debian 8.6 doesn't because its bootloader isn't signed
How can I replace the bootloader that is present in Debian with the one found in Ubuntu so that it boots with the aforementioned situation?
And even if it (Debian) boots successfully in live environment,
What can I do to make sure it continues to do so after it's installed?
