I’m guessing failed to prepare your disk properly for a UEFI installation; guessing because insufficient information was provided to form an accurate assessment.
A UEFI installation is presumed, being that this has been the default for at least the last decade. In future, please indicate in your first post that you have a Legacy/MBR based installation.
And if that time comes, perhaps your own attitude will be reflected back at you, which naturally will not be very productive.
