So I did get this resolved. After trying a few different things I noticed that even when using an entirely new boot drive I was still being shown boot options that I had manually created on my old boot drive. This made me remember I had a second USB plugged in that I would periodically backup my boot to when making changes. For some unknown reason Unraid deciced to start booting off that second USB.
Once I removed the second USB, recreated my boot flash, and powered on my system was able to boot normally again. Weird problem but happy it wasn't anything too terrible.
Thanks @Squid and @JorgeB for trying to help!
