A repair installation is used to fix issues within the current operating system without removing user data, applications, or settings. It is particularly useful when system files are corrupted, causing boot failures, as it can replace the damaged files while preserving the user’s data and configurations.

After an OS upgrade, if some hardware components are not functioning correctly, the most likely cause is that the necessary drivers are either not installed or are outdated. Drivers are crucial for the operating system to communicate with and properly utilize hardware components. Updating or reinstalling the correct drivers for the new OS version can resolve these issues and ensure hardware compatibility.

Before upgrading an operating system, backing up files and user preferences is crucial to prevent data loss. This step ensures that personal data, configurations, and important files are safely stored and can be restored if the upgrade process encounters issues or data gets accidentally erased.

Checking for application and driver support before an OS upgrade is crucial to ensure that all critical software and hardware peripherals continue to function properly after the upgrade. This step helps avoid compatibility issues that could disrupt user productivity or necessitate additional troubleshooting.

Using an external USB drive for diagnostics and recovery aligns with the policy of avoiding internal drive tampering, providing a non-intrusive way to troubleshoot or recover systems. PXE, internal recovery partitions, and dual-boot setups involve internal system modifications or network dependencies.

When performing remote network installations, a significant challenge is managing network bandwidth to avoid overwhelming the network and disrupting other critical network services. Large-scale deployments can consume substantial bandwidth, potentially affecting the performance of other applications and services running on the network. Planning and possibly scheduling installations during off-peak hours can mitigate this issue.

A clean install is the most appropriate method for a machine heavily infected with viruses. This process removes all data from the drive, including the operating system, applications, and viruses, providing a fresh start. It’s the best way to ensure the removal of malware and any corrupted files.

An upgrade installation allows the operating system to be updated while preserving user data, applications, and settings. This method is ideal for corporate environments where maintaining continuity of applications and data is crucial. Clean installs, image deployments, and recovery partitions are options that could potentially erase existing data or require reinstallation of applications, which is not desirable in this scenario.

Preboot Execution Environment (PXE) allows computers to boot through the network interface independently of data storage devices or installed operating systems. This method is ideal for deploying operating systems to multiple computers simultaneously, especially when they lack an existing OS, eliminating the need for physical media like USB drives or optical media.

Changing the boot order in BIOS settings to prioritize the optical drive over the hard drive or SSD is crucial for booting from optical media. Disabling Fast Boot and enabling CSM might help in some scenarios, but prioritizing the boot order directly addresses the issue. Optical Drive Emulation is not a common BIOS feature for boot issues.

For a clean installation of an operating system using a USB flash drive, the drive must contain a disk image file, specifically an ISO file, that has been properly written to the USB. This process involves not just copying the ISO file to the USB but using a specialized tool to make the USB bootable and unpack the ISO contents in a way that the server can boot from it. The ISO file is a complete image of what would be on an installation CD or DVD, making it the correct choice for this scenario. Compressed archives, executable installer files, or individual system files are not sufficient on their own to create a bootable environment for an OS installation.

Hot-swap capability is essential for replacing a failing drive in a RAID 5 array without interrupting data access. This feature allows drives to be removed and replaced while the system is powered on and operational, ensuring continuous availability of data. Solid-state drive technology, USB connectivity, and wireless data transfer do not inherently support the seamless replacement of drives in an active RAID array without downtime.

The network boot method, often referred to as PXE (Preboot Execution Environment), allows computers to be booted over the network where they can download and install an operating system image from a server. This method is ideal for deploying images to multiple computers simultaneously, especially when they lack an installed OS

GPT (GUID Partition Table) is recommended for dual-boot systems as it supports larger drive sizes and more partitions than MBR (Master Boot Record). GPT is compatible with both Windows and Linux, making it an ideal choice for a dual-boot setup, ensuring both operating systems can be installed on the same drive without partition size limitations.

Solid-state drives (SSDs) provide significantly faster read and write speeds compared to optical media like CDs or DVDs. This speed advantage makes SSDs a preferred choice for booting and installing operating systems, leading to quicker installation times and overall system performance improvements.

A repair installation is most appropriate when the operating system’s core files have become corrupted, but the user’s data remains unaffected. This method repairs the OS by replacing the damaged files with fresh copies while preserving applications, settings, and personal files, thus avoiding the need for a complete reinstall and data restoration.

USB Legacy Support enables BIOS to recognize USB devices at boot time, which is essential for booting from a USB drive.

Including third-party drivers in the OS image ensures that all deployed systems have the necessary drivers for specific hardware used in the company, such as printers, scanners, and specialized peripherals. This step is crucial for compatibility and operational efficiency, avoiding the need for individual driver installations post-deployment.

NTFS (New Technology File System) is the preferred file system for Windows environments due to its support for large file sizes, enhanced security features, and better data recovery options compared to FAT32. NTFS is suitable for both internal and external drives when installing Windows.

Hot-swappable SATA drives are designed to be removed and replaced while the system is still running, eliminating the need for downtime during upgrades or replacements. This capability is crucial for maintaining server operations in an enterprise environment. While external USB drives can also be connected without shutting down, they do not offer the same level of integration and performance as internal SATA drives designed for hot swapping.

Using a virtual machine (VM) allows the organization to upgrade its computers to Windows 10 while still providing an environment where legacy applications can run. The VM can emulate the older operating system, offering a separate, dedicated space for running applications that are not compatible with the new OS. This approach ensures business continuity without sacrificing the benefits of upgrading.

Remote network installation allows administrators to deploy operating systems to multiple machines simultaneously over a network. This method significantly reduces the time and effort required to manually install the OS on individual systems, making it an efficient choice for large-scale deployments in enterprise environments.

A recovery partition is a segment of the hard drive set aside by the manufacturer to store a copy of the operating system and factory settings. It is used to restore a computer to its original state, which is helpful in cases of system failure or when a clean start is needed without using external installation media.

USB drives can be used as an external boot method to install operating systems. They are portable, widely supported, and can carry OS installation media, making them a convenient choice for installations where internal storage is not available or viable.

Using a driver management solution to inject drivers post-deployment allows for flexibility and ensures that each system gets the correct drivers based on its hardware configuration. This approach avoids bloating the base image with unnecessary drivers and addresses the diversity of hardware in a network more efficiently than embedding drivers or creating multiple images.

Booting from a USB drive with a live OS allows the user to bypass the computer’s internal storage, providing a minimal operating system environment for diagnostics and troubleshooting. This method is practical for running utilities without needing the PC’s primary OS to boot.

GPT is recommended over MBR for drives larger than 2TB because MBR has a limitation that does not support drives over 2TB in size. GPT does not have this limitation and supports larger drives, making it the preferred choice for modern, high-capacity storage solutions. GPT also provides more partitions and better data integrity.

The Trivial File Transfer Protocol (TFTP) server is a lightweight, simple file transfer protocol that is used in the PXE boot process. It hosts the boot files (including the bootloader and kernel) that PXE clients download over the network to initiate the boot process. TFTP is chosen for its simplicity and efficiency in serving the small, necessary files to PXE clients.

A third-party utility like Rufus or Etcher is commonly used to create a bootable USB drive from an ISO image. These tools are designed to write ISO images to USB drives, making them bootable.

FAT32 is the recommended filesystem format for a flash drive intended to boot PCs in UEFI mode because it is widely supported by UEFI firmware across different hardware platforms.

BIOS/UEFI settings on client computers must be configured to enable network booting, often referred to as PXE boot. This involves setting the network card as the primary boot device, allowing the computer to seek out network-based installation media before attempting to boot from local storage.
