Hi James, Thank you for your response I do like the idea of booting over the network using PXE however I don’t currently have tufts server set up so was using NFS a what I thought would be a quick solution.
Tell me if you set up the PI to PXE boot can you revery back to the Standard SD boot t it won’t PXE boot?
