I uploaded a new Ubuntu image onto my server and then I tried deploying it out (both onto new computers and old ones), I keep getting this error message and it exits me out of my active task. Not sure what settings do I toggle (This is after I finished removing the structure of the GPT partition with "sgdisk -Z /dev/sda"). It uploads successfully but deploys with errors.

Probing devices to guess BIOS drives. This may take a while.

Please advise.

Sorry, lost track of this post, been getting a lot of inquiries lately. I would disable the update grub function. It's legacy and I don't think it really does anything anyway.
Global->Imaging Scripts->Edit Core Scripts->Select cd_push from the drop down

Search for function update_grub()

On the line before log " ** Checking if grub is required ** "
put return 0

Should look like

function update_grub()
  return 0
  log " ** Checking If Grub Is Required ** "

Click update
