Question about creating options

[eulakowal]

Hello,
I am a newbie and have a question. What are the three options (Legacy, VHD, VHDx I think) after formating the device?

The 'Legacy' installation mode installs Windows directly into the target boot partition on the physical USB drive, and the VHD/VHDX installation mode installs Windows on the VHD/VHDX file that is stored in the target boot partition. When you choose to use VHD/VHDX mode, there is only one VHD/VHDX file in the boot partition on the physical USB drive, and all Windows files are stored in this VHD/VHDX file. After booting Windows from a VHD(X)-based USB drive, you will see two partitions, one is the C: drive located on the VHD(X) file and and the other is the drive located on the USB drive where the VHD/VHDX file is stored.
