Please try adding network driver to the RIS installation.
Below is the guide to setup network driver for RIS installation
Below is the link to download drivers
Thank you for your response.
I've now added the driver packages in the link you added, also the driver files from the download page of the actual drivers for the motherboard. the x64 bit boot now works.
However the x86 architecture to the x86 bootfile, with all the added x86 version driver still gives me the same error.
