I've installed Gentoo on a few different machines before, but this laptop is being a real pain. It's a Samsung NP-QX411-W01US if that matters. It uses a bios, but has some weird UEFI emulation that is disabled by default. This laptop was released just as EFI was starting to be a thing.

Anyways I've tried both MBR and GPT, grub2-install reports no errors either way. But upon boot the BIOS says no boot devices. My only other thought as of this moment is to try UEFI, but CentOS and Debian have no issues using MBR which makes this strange.

TriadicTek,

Welcome to Gentoo.

Be sure to set the bootable flag on the MSDOS partition - even if you use GPT.
In BIOS mode, some systems check that the bootable flag is is set on exactly one partition.

Yes, that was exactly the problem. I'll have to make a mental note of that, I'm certain to run into again in the future.
