Installing OS - Choosing an OS

Selecting an Operating System

  • Understanding which operating system (OS) to install is crucial for business settings.

  • Key considerations:

    • Decision Propagation: Check if the decision on which OS to use has already been made.

    • Specific OS Requirements: Some organizations or services mandate a specific OS. If so, the choice is straightforward.

    • Software Requirements: Identify what software will need to run on the device. This could dictate the OS choice:

      • Software may be designed for specific operating systems.

      • Some software is cross-platform, meaning it can run on various operating systems.

    • Hardware Compatibility: Ensure that the hardware will support the chosen OS:

      • Modern operating systems typically support common hardware well.

      • Be cautious, as some manufacturers restrict their OS to specific hardware.

    • CPU Architecture: Be aware of the different CPU architectures (32-bit and 64-bit).

      • The chosen OS must be compatible with the CPU architecture (e.g., a 64-bit CPU should use a 64-bit OS).

Installing the Operating System

  • After selecting an OS, understand the installation process:

  • Preinstalled Operating Systems: Many computers come with an OS pre-installed:

    • When booted, the computer will continue from the vendor installation point.

    • Final setup may include:

      • Choosing a computer name (host name).

      • Configuring network settings.

  • Installing from Scratch: You may also need to install an OS from scratch using different installation media:

    • OS options include:

      • Physical disks (CDs/DVDs).

      • USB drives for installation.

      • Internet reinstalls directly from the OS manufacturer.

  • Efficiency in Installation: As an IT specialist, you’ll need scalable solutions for multiple installations:

    • Using one disk is not time-efficient for multiple computers.

  • Scaling Considerations: While focusing on individual installations currently, keep scalability in mind for future scenarios.

  • USB Drive Usage: For single-computer setups, USB drives are a common choice:

    • Some manufacturers like Windows offer specialized USB drives with pre-loaded installation images.

    • Linux installations can be done using any generic USB drive.
