cheers for the reply ,
i managed to change the file , but its not working for me ,
i seem to only be able to install the GUI version ,2nd option
no matter how new installs i do, whether manual or 1 click ,
in the headless the 424 pro cannot find the usb , but when booting to GUI it finds it fine ?!
also in the headless it returns to the main bios without any options for booting until i power cycle ,
i did have this running proxmox ,might to return to proxmox and run unraid in a vm ?
