I have 4 HP 6300 , desktop computers.
There is no issue uploading my base image but when I try to deploy it, I get a black screen with a blinking cursor.
The workstations communicate just fine with FOG.
I boot from my network card, I can register the workstation, it sends the inventory, reboots and comes up to the black screen. I can get into the partition information and that is where I found the “Error /dev/sda: unrecognized disk label” error.
All the computers are the same.
In the past couple days, I have searched and read anything close to my problem, with no luck!!

I would appreciate any help, this is making me crazy!
