Is it just getting stuck after those messages? You could try chrooting into your system and reconfigure, it could be that something got corrupted after the power outage that affects the boot process. The manual has a good section on how you would do that: https://guix.gnu.org/manual/devel/en/html_node/Chrooting-into-an-existing-system.html -- s/Fred[re]+i[ck]+/Fredrik/g
