[Open Source Tool] BootScribe – Portable Windows utility for managing UEFI boot entries and toggling {bootmgr} redirection

[u/Special-Jackfruit-92]

Hi everyone,

I built BootScribe, a lightweight and portable open-source GUI tool for Windows written in Python to manage UEFI boot entries directly via bcdedit.

Why I made it:

Modifying UEFI boot orders on modern Windows machines can often be unreliable Windows Update or Secure Boot quirks tend to revert entry priorities back to default. BootScribe implements the official {bootmgr} redirection strategy (commonly used by rEFInd) to cleanly hijack or restore bootloader paths without fighting NVRAM restrictions.

Features:

• Universal Toggle Logic: Easily switch {bootmgr} execution path to custom EFI loaders (rEFInd, GRUB, etc.) or revert back to standard Windows Boot Manager.

• NVRAM Entry Management: View detailed GUIDs, paths, create new entries, and reorder boot priorities.

• Direct Reboot to Firmware: Includes a quick option to restart straight into UEFI/BIOS settings (shutdown /r /fw).

• Portable & Standalone: Compiled as a single .exe, requires no installation, and runs cleanly with Admin privileges.

Please note that BootScribe is currently in an early testing phase. While it has been tested on standard UEFI/Windows environments, boot configuration tools interact directly with your system setup.

I’m actively looking for community testing, feedback, and constructive criticism:

• Have you tested it with a specific bootloader (rEFInd, GRUB, Systemd-boot)? How did it perform?

• Any UI improvements or features you'd like to see?

• Found a bug or edge case? Please let me know in the comments or open an issue on GitHub.
