Acronis Snap Deploy started supporting disks with GUID partition tables (GPT) and dynamic disks in version 4.
Acronis Snap Deploy 5 supports GUID Partition Table (GPT) partitioning scheme. Dynamic volumes (in Windows) can be deployed as basic volumes only.
Acronis Snap Deploy 4 supports GUID Partition Table (GPT) partitioning scheme. Dynamic disks currently are not supported for imaging and deployment. Detailed information here.
Acronis Snap Deploy 3 and 2 do not support dynamic Disks or GUID Partition Tables (GPT). If there are dynamic or GPT disks on your machine, Acronis Snap Deploy will not detect them in Windows or from Acronis Bootable Media. You can always convert a GPT disk to an MBR disk that is supported by Acronis Snap Deploy. See Microsoft TechNet article: Change a GUID partition table disk into a master boot record disk.
