Issues with PXE boot. We are confident we have DHCP server redirecting to Management server correctly, however pc's are not picking up correct boot directory/file.

unable to boot in pxe mode error "E74" so removed option 43 from DHCP (since there is only one pxe server) now getting error "prepxe error invalid pxe server list found"


The option 060 PXEClient was missing.



We saw that the option 060 PXEClient was missing so we added all the 4 options which are necessary for the PXE  Clients to respond to the PXE  Server and added

060 - PXE  Client

043 - Vendor ID

066 -PXE Server (IP  ADDRESS or SERVER  name)

067-Bstrap.0 file location \x86pc\Bstrap\Bstrap.0
