Title, scoured Google, asked the Odin Project Tech Support and Ask Ubuntu and didn't get a response, questions here and here didn't help, totally at my wits end. There's so much info out there I don't even know what's relevant/helpful information, but here's the gist - I followed the instructions here, from "Installing Ubuntu" down.
It was a nightmare to get it to recognize my free partition on my one and only drive (SSD), but it finally did, I got an "Installation Complete", and then it said I needed to restart to use Ubuntu. I did, and it went straight to Windows. Not only that, but in the BIOS config screen there's no option for Ubuntu at all. It's just like it doesn't exist. I even put my bootable USB back in to access the GRUB (only way I could figure out how to access GRUB, instructions I followed online to hold down Shift while starting up didn't work), and there's not on-disk Ubuntu option there either.
Fast boot is disabled, secure boot is enabled.
Any help is HUGELY appreciated, and I'll provide any information asked for if it's helpful, I just didn't want to overload here with irrelevant stuff.
