Symantec Partition Table Editor — The Symantec branded version of this classic Partition Table Editor

PTEDIT Partition Table Editor by PowerQuest — Using the original PowerQuest version to modify partition tables.One of the key features is its ability to toggle the active partition flag (changing the boot indicator from 00 to 80) without requiring a reboot or using third-party boot tools.

Even better, it can be stored and run directly from a USB flash drive, making it a truly portable partition editing tool.

Is PTEDIT Still Safe to Use?

Yes — as long as you understand what you're doing. PTEDIT modifies the Master Boot Record (MBR) directly. Misuse can lead to an unbootable system. Use only if you're experienced with partition structures or working in a test environment.

Modern Alternatives

While this partition editing tool is useful for MBR systems, newer tools support GPT partition tables and modern UEFI environments. Consider these alternatives:

GParted Live – A free Linux-based partition editor
MiniTool Partition Wizard – A full-featured Windows partition manager
EaseUS Partition Master – Another popular GUI-based partition tool
DiskPart – Built-in Windows CLI partition utility

Conclusion

If you're working on legacy systems, PTEDIT remains a powerful and lightweight tool for directly editing partition table entries from within Windows. Though discontinued, it still finds use among tech savvy users and IT professionals. Just be sure to use it with caution, and always make a backup before making any changes to your disk structure.
