I have attempted to install a network based image using Microsoft system center configuration manager (SCCM) via Parallels (latest version) from a virtual machine. On other machines (PCs), I can press the F12 key upon booting the virtual machine to go to BIOS and update the settings to enable PXE boot. I have looked up ways to enable the virtual machine on the Intel iMac to boot to the designated SCCM server but with no success.
Please help. Thanks.
