Small Engine Gets DIY EFI Upgrade

This blog by RFSysadmin saved my #Proxmox install after the upgrade from 8 to 9. It seems like the #EFI boot sequence got blasted in the update (i thought, i was careful) and proxmox 9 rebooted into the BIOS.
Long story short: Boot into the rescue enviroment (login is your root login)
fix the EFI settings like mentioned in the blog
Reboot and keep enjoying that #homelab
