Can you boot off of a MicroSD card?

I just received my Framework laptop and wow… I am really satisfied with the build quality. Unfortunately I am not able to install an OS as of yet. I’ve created a bootable image on a MicroSD card and tested the MicroSD card on an old laptop to make sure it will boot to it and it does boot. My Framework laptop will not recognize the bootable card. Any thoughts or insights? Thank you in advance!

Forgot to add - The error is Default Boot Device Missing or Boot Failed. Going to verify that the HDD is installed correctly.

Checked the HDD and verified all connections. Still not booting from the MicroSD card using the MicroSD card reader. :crazy_face:
