Hi.
Does it belong to domain? If it belongs corporate and joined to domain it can be Bitlocker protected.
But if it's a standalone you can try Acronis, Norton Ghost imaging softwares or you can use tools from Microsoft such from command line:
Diskcopy c: d: /v (for this method you need to boot with any boot disk which has command line
