These are a few tips to help get Debian 11 running on TrueNAS 12. I tried to install Debian 12, however both Graphical and Text installers had issues running.

Set the VNC resolution¶

• After adding the VM, expand the VM options and click on Devices .
• Next open the options for the VNC device
• Set the Resolution to 800x600
• Click Save

Fix EFI¶

• Power off the VM and remove the CDROM device from the VM
• Power on the VM, the EFI boot will fail
  Wait until the EFI shell appears, the press Esc
• Exit the EFI shell
  

  exit
  

• Navigate to the Boot Maintenance Manager
• Select Boot from file -> <NO VOLUME LABEL ... GPT ...> -> EFI -> debian -> grubx64.efi
• Login as root and type the following commands to fix the EFI boot issue
  

  mkdir -p /boot/efi/EFI/BOOT/
  cp /boot/efi/EFI/debian/grubx64.efi /boot/efi/EFI/BOOT/bootx64.efi
  reboot
