Měl jsem tam (asi) TeachMePCB a baterka asi umřela a EFI si nepamatovalo nic, tak nebootovalo. Nabootoval jsem z instalačky gentoo, našel řadek s efibootmgr a aplikoval ho a zase to šlo. Ale systém je neupdatovatelný a nemám tam nic, o čem bych věděl, že to chci, takže znova od začátku.

Chci to na chatičku, protože Mahoro už nezvládá KiCad a tohle tam může sedět nafurt.
