Installationsmedie

Installationsmedie refers to removable or virtual media that contains an installation package or disk image used to install an operating system, software, or system updates on computers or devices. Such media is prepared to be read by a device during the boot process and may carry automation scripts or drivers needed for the installation.

Common forms include USB flash drives, writable DVDs or Blu-ray discs, external hard drives, or network-based images such as ISO or WIM files that can be mounted or deployed via PXE. In modern contexts, USB drives and ISO-based installers are standard for personal and small-scale deployments, while enterprise environments often use network deployment tools for large-scale installations.

Installationsmedie are created by obtaining official media from the software vendor, then writing the image to media with appropriate tools. Verification with checksums or cryptographic signatures helps ensure integrity and authenticity, reducing the risk of tampered or corrupted installers.

To use, the device is booted from the installationsmedie, and the installer guides the user through setup steps. In unattended or automated deployments, configuration files control settings, partitions, and software selections.

Security and best practices include obtaining media only from trusted sources, keeping media up to date, verifying signatures, and ensuring compatibility with secure boot. After installation, enable encryption where appropriate and protect the installation media from loss or theft.

Lifecycle considerations involve refreshing media with new OS or software releases and employing network-based deployment as a complement or replacement for physical media in organizational contexts.
