GeminiLake Chromebook No Menu

I have a Lenovo Chromebook (PHASER360) and i tried to run linux on it
I got coreboot sucessfully installed but when i went to the boot menu i cant switch to usb i tried going to efi shell and all i see is fs1 with emmc i think my chromebook isnt recognizing it

Model: Lenovo Chromebook 500e 2nd Gen

Have you tried using another USB drive?

I haven’t because I only got 1 right now
might’ve been a bad idea lol

what does this even mean?
