Deploying DSM 7.x on Hyper-V using the Tinycore Redpill loader is a complex but rewarding process for virtualization enthusiasts. The procedure requires careful attention to storage controllers (IDE vs. SCSI) and driver injection.

If you simply want a free NAS on Hyper-V, consider TrueNAS Core (officially supports Hyper-V) or OpenMediaVault (no legal grey areas). They lack the polish of DSM 7, but they are legal and stable.

The critical success factor in this deployment is the Virtual Machine generation and storage controller configuration.
