What UEFI Boot Manager is

UEFI Boot Manager is a free command-line tool for managing UEFI boot options on Linux and Windows. It can list boot entries with their order, active status, and IDs, then change the permanent boot sequence while preserving omitted entries at the end in their existing relative order. It can also set or clear a one-time next-boot override without changing that permanent sequence. A menu-driven interactive mode supports the listed operations and returns to the menu after errors. The tool requires Python 3.12 or later and UEFI firmware, but has no external Python dependencies. Commands need elevated privileges: Administrator access on Windows or root access on Linux. Its Windows backend uses bcdedit; Linux uses efibootmgr, which may need to be installed separately. It does not support legacy BIOS, and unsupported operating systems produce an error. The project is licensed under MIT, which permits use and modification subject to its conditions and provides the software without warranty.

Who it suits

It suits Linux or Windows users who need to view or manage UEFI boot entries and can run commands with elevated privileges. It is not for legacy BIOS systems.

What it does well

Lists boot-entry order, status, and IDs
Reorders entries while preserving unspecified ones
Sets or clears a one-time boot override
Interactive mode returns to the menu after errors

What to know first

Requires Python 3.12 or later
Requires Administrator or root privileges
Linux may require separate efibootmgr installation
Does not support legacy BIOS

Limits

The tool requires UEFI firmware and does not support legacy BIOS; unsupported operating systems produce an error. Linux use depends on efibootmgr, which may need to be installed separately.

Getting started

Open the project repository on GitHub.
Ensure the system uses UEFI firmware and has Python 3.12 or later.
On Linux, install efibootmgr if it is not already available.
Run commands with Administrator privileges on Windows or root privileges on Linux.

Verdict

UEFI Boot Manager covers viewing, reordering, and one-time overrides for UEFI boot entries across Linux and Windows. Check the Python, firmware, platform-backend, and privilege requirements before using it.
