Hi,
Translated by Google from Swedish

Is it possible to add an EFI system partition to a server already
running Debian 12?
How do I do it?

I would disconnect the 2T drives, install a small, fast, security erased SSD, connect the SSD to the motherboard first HBA port, boot into Setup, do a "Factory Reset", configure settings as desired (e.g. UEFI mode), and do a fresh install of Debian onto the SSD with a 1G ext4 boot, 1G swap, and everything else on ext4 root (encrypt swap and/or root as desired). Once that is up and running, reconnect the 2T drives, disable the boot flag on sda1 and/or sdb1, install/configure LVM to access the contents of your 2T drives, and install/configure software.
