Ghost 11.5 is much older than the Skylake chipset but as long as you can boot a version of WinPE with the correct drivers for the machine NIC and SATA chipsets then you should be able to image.
I have tested WinPE 2.x with USB3 drivers some years ago and all was OK. However, it is hard to get Vista drivers for WinPE 2.x so better to use WinPE 3.1 or upgrade to GSS 3.1
