Reinstallation Methods: How To Reinstall Operating System

How to reinstall operating system

Reinstalling your operating system can be necessary for various reasons, such as resolving persistent issues, upgrading to a newer version, or replacing a corrupted system. There are several methods available for reinstalling the operating system, each with its own advantages and considerations.

Creating a Bootable USB Drive

Creating a bootable USB drive is a common method for reinstalling the operating system. Here are the steps involved:

  • Download the operating system ISO file from the official website.
  • Obtain a USB drive with sufficient storage capacity (8GB or larger is recommended).
  • Use a tool like Rufus or UNetbootin to create a bootable USB drive from the ISO file.

Configuring BIOS Settings to Boot from USB

Once the bootable USB drive is created, you need to configure your computer’s BIOS settings to boot from it:

  • Restart your computer and press the designated key (usually F2, F10, or Del) to enter the BIOS settings.
  • Navigate to the “Boot” or “Boot Order” section and set the USB drive as the first boot device.
  • Save the changes and exit the BIOS settings.

Clean Installation vs. Repair Installation

There are two main types of operating system reinstallations: clean installation and repair installation.

If you’ve tried all the other troubleshooting tips and your PC is still running slow, you may need to reinstall the operating system. This will erase all of your data, so be sure to back up your files first. For a more detailed guide on how to fix a slow PC, check out this article: How to fix slow PC . Once you’ve reinstalled the operating system, your PC should be running like new again.

  • Clean Installation: This involves wiping the entire hard drive and installing a fresh copy of the operating system. It is the most thorough method but also requires backing up all important data beforehand.
  • Repair Installation: This attempts to repair the existing operating system without erasing data. It can be useful for resolving specific issues but may not be effective for all problems.

Operating System Selection
