gptgen for Windows

About the utility

gptgen is a lightweight Windows tool that converts disks formatted with the traditional MSDOS/MBR partition table to the newer GPT (GUID Partition Table). It performs the conversion without wiping existing partitions or files, making it a practical choice for users who want to update their drive partitioning scheme while keeping their data intact. The program runs from the command line, which suits users comfortable with terminal-style operations.

• Preserves all current files and partitions during conversion
• Designed for execution on Windows systems
• Operates via command-line interface for scriptable or manual use
