Differences Between Legacy, VHD, and VHDX Formats - smokeexceed - 11-19-2025
Hi everyone,
I’m new here and have a quick question. After formatting a device, I see three options—Legacy, VHD, and VHDX. What do these choices mean?
Thanks in advance for any clarification!

The 'Legacy' installation mode installs Windows directly to the physical drive, and the VHD/VHDX installation mode installs Windows on the VHD/VHDX file that is stored in the physical drive. When you choose to use VHD/VHDX mode, there is only one VHD/VHDX file in the physical drive, and all Windows files are stored in this VHD/VHDX file.
