Bootloader

A bootloader is a small program on a computer or mobile device that is responsible for the startup processes of the operating system. It is activated as soon as the device is turned on.

The bootloader acts as an intermediary between the device’s hardware and OS thatinitializes hardware, checks basic functions, organizes device memory and loads the OS.

Bootloader in everyday administration

For IT professionals, understanding the bootloader is important for working with various aspects of the boot process. This includes configuring the bootloader according to specific requirements, as well as diagnosing and troubleshooting startup problems.

The bootloader plays an important role in a trusted operating system startup process and in preventing attacks on the boot process. Boot loader mechanisms such as Unified Extensible Firmware Interface (UEFI) or the Trusted Platform Module (TPM) increase the security of the boot process.

Configure boot loader

For example, a UEM solution can be used to configure the boot order of devices, authentication methods or the behavior during the boot process. If operating systems are installed on multiple devices at the same time, a UEM solution ensures that the desired boot loader settings are centrally defined, comply with current policies and are distributed uniformly.
