This Python Script enables one to create, modify, suppress rows from the NVRAM table which contains the OS starting up programs and also to modify the classification on the Bootorder table.
In fact, according to the indications it receives from the user and to the NVRAM content, it composes and launches the “efibootmgr” commands which could have been (on Linux) laboriously created manually in a terminal to reach the same result.
The used “efibootmgr” commands are displayed at the bottom of each window before being executed.
