@Base2Nathan Good to hear you figured it out. You might wonder why the config George suggested doesn’t use option tftp-server-... and option bootfile-name at all. There are two places in DHCP packets where PXE boot information can be placed. One is DHCP options as you have used them. But there is also next-server and filename what are fields within the DHCP header information. Take a closer look at the wireshark dump…

@clickwir Any news on this?

You are trying to boot the I.S.O. over the network. The way I recommend you do this for pxe access in your company is to extract the content of the iso to a folder of your choosing then give proper access to the folder for the fog server using the exports file. examples can be provided if im understanding what your trying to do?

Hey, after tessting it really looks like the problem is on that SSD. Could deploy and upload on other clients. I guess the first imaging tool brokes it. But after all fog is better than that anyway. Thank you for your help!
