Hello everybody, I did an upgrade 8 to 9 and everything worked out without any errors. After an reboot it suddenly goes to bios, Secure boot is disabled, I did verify the boot order and it is in UEFI mode. Then I started Proxmox from an USB stick in rescue mode (9.2.1) and boom I was in the system. As far as I understand it is a question of grub? How can I fix this? proxmox-boot-tool? I have no idea how to us that. Thanks for some help
