Preparing for Installation: Essential Prerequisites

Before embarking on the installation process, meticulous preparation is paramount. Ensuring your system is ready will pave the way for a seamless and successful installation.

Downloading the Installation Media

The cornerstone of any installation is the installation media. This typically takes the form of an ISO image, which needs to be downloaded from a trusted source.

Verifying the Integrity of the ISO Image

Data corruption during download is a real risk. It can lead to installation failures or, worse, a compromised system. Therefore, verifying the integrity of the downloaded ISO image is an absolutely crucial step.

Obtaining the Checksum

The first step is to obtain the checksum for the ISO image. This is a unique digital fingerprint, typically provided by the source where you downloaded the image. Common checksum algorithms include SHA-256 and MD5. You can usually find the checksum listed alongside the download link.

Calculating the Checksum Locally

Next, you need to calculate the checksum of the downloaded ISO file on your system. This process depends on your operating system.

  • Linux: Utilize the sha256sum command (for SHA-256) or md5sum command (for MD5) in your terminal. For example: sha256sum your_iso_image.iso.
  • macOS: Open Terminal and use the shasum -a 256 your_iso_image.iso (for SHA-256) or md5 your_iso_image.iso (for MD5) command.
  • Windows: Several utilities can calculate checksums, including certutil -hashfile your_iso_image.iso SHA256 (for SHA-256) in the command prompt or PowerShell, and third-party tools like HashMyFiles or 7-Zip.
Comparing the Checksums

Finally, compare the checksum you calculated with the checksum provided by the download source. If they match, your ISO image is intact. If they differ, the image is corrupted, and you need to download it again. Failure to verify the checksum is a common pitfall, so always perform this check.

Creating a Bootable USB Drive

Once you have a verified ISO image, the next step is to create a bootable USB drive. This allows you to boot your system from the installation media.

Choosing the Right Tool

Several tools can create bootable USB drives. The best choice often depends on your operating system and the type of ISO you are using.

  • Rufus (Windows): A popular and user-friendly tool known for its speed and reliability. It handles various ISO images and boot options effectively.
  • Etcher (Cross-Platform): A simple, cross-platform tool with a clean interface. It’s easy to use and works well for most ISO images.
  • Ventoy (Cross-Platform): A versatile tool that allows you to place multiple ISO files on a single USB drive, selecting which one to boot from a boot menu. This is very useful if you want to be ready to install several OSes from the same USB.
  • dd Command (Linux/macOS): A powerful, but potentially dangerous, command-line tool. It’s effective but requires precise syntax; incorrect usage can lead to data loss.

Formatting and Writing the ISO

Regardless of the tool, the process typically involves these steps:

  1. Select the USB drive: Carefully choose the correct USB drive from the list. All data on the selected drive will be erased.
  2. Select the ISO image: Browse and select the downloaded and verified ISO image.
  3. Choose the write mode (if applicable): Some tools offer options like “GPT for UEFI” or “MBR for BIOS.” Select the appropriate option for your system’s firmware (UEFI or BIOS).
  4. Start the process: Initiate the writing process. The tool will format the USB drive and write the ISO image to it.

Verifying the Bootable USB Drive

After the writing process is complete, the tool may automatically verify the drive. If not, it’s recommended to verify the bootable drive by attempting to boot from it on another system or in a virtual machine.

Understanding System Firmware: BIOS and UEFI

Your system’s firmware, the software that initializes your hardware before the operating system loads, plays a crucial role in the installation process.

BIOS (Basic Input/Output System)

BIOS is the older firmware standard. It uses a Master Boot Record (MBR) partitioning scheme and has limitations regarding drive sizes and boot options.

UEFI (Unified Extensible Firmware Interface)

UEFI is the modern standard, offering significant advantages over BIOS:

  • GPT Partitioning: UEFI supports the GUID Partition Table (GPT) partitioning scheme, which removes the limitations of MBR.
  • Secure Boot: UEFI can implement Secure Boot, which helps protect against malware by verifying the integrity of the operating system’s bootloader.
  • Faster Boot Times: UEFI typically offers faster boot times.
Identifying Your System’s Firmware

The easiest way to determine whether your system uses BIOS or UEFI is to:

  1. Enter the Firmware Setup: Restart your system and repeatedly press the designated key (usually Del, F2, F12, or Esc) to enter the firmware setup (BIOS or UEFI).
  2. Look for UEFI or BIOS: In the firmware setup, look for a clear indication of whether your system uses UEFI or BIOS. It might be in the boot options section or system information.
  3. Check Boot Options: In the boot options, look for the boot device and how it is listed. If the USB drive is listed with “UEFI” in its name, you are using UEFI.

Backing Up Your Data: The Critical First Step

Before proceeding with any installation, backing up your data is absolutely crucial. Data loss is a real risk during installations, so protect your important files.

Choosing a Backup Method

Several backup methods are available, each with its advantages and disadvantages.

External Hard Drive Backup:

A simple, reliable method involves copying your data to an external hard drive. Consider creating a full system image for a complete recovery.

Cloud Backup:

Cloud backup services provide offsite storage. Choose a reputable provider with sufficient storage capacity. Make sure you have a stable internet connection during backup and restore.

Network Attached Storage (NAS):

A NAS device provides a centralized storage solution on your local network. It offers automatic backups and easy access to your files.

Verifying the Backup

After creating the backup, it is imperative to verify its integrity. Attempt to restore a few files from the backup to ensure that the backup process was successful and that the data is accessible.

Booting into the Installation Environment

With the preparatory steps complete, it’s time to boot into the installation environment.

Accessing the Boot Menu

To boot from your newly created USB drive, you need to access the boot menu.

Identifying the Boot Menu Key

The boot menu key varies depending on your motherboard manufacturer. Common keys include Del, F2, F10, F12, Esc, or the key indicated by the motherboard’s manual.

Booting from the USB Drive

  1. Restart your system: Ensure the USB drive is connected.
  2. Press the boot menu key: Immediately after the system restarts, repeatedly press the boot menu key to access the boot menu.
  3. Select the USB drive: In the boot menu, select your USB drive as the boot device. Be mindful of UEFI vs. non-UEFI boot options. If you are using UEFI, choose the entry that has “UEFI” in its description.

Once you’ve successfully booted from the USB drive, you will enter the installation environment. The specifics of the initial setup vary depending on the operating system you are installing.
