It is not advisable to reformat your computer for some minor reasons because it poses a possible risk to your Hard Disk Drive (HDD).

However, if you want to know the valid reasons why you need to freshen up your system, then read the following.

  • Laptop Does Not Start. If your computer does not boot due to some file registry errors, instead of draining all the possible cmd keys, better just reformat your laptop to solve the bug. Fixing the Windows registry is risky since it contains the necessary protocols and configuration options of your computer’s operating system.
  • Full Hard Disk Drive. Another valid reason why you need to reinstall a new operating system is when the hard disk of your computer is already full. While you can do manual delete and perform a file backup, it would be the best for your computer to load a new operating system.
  • System Errors. Viruses, malware, and other malicious files from the internet will cause your laptop to boot longer than usual. There is third-party software that offers the capability to fix system errors, but most of them just worsen the situation. The best remedy for overwhelming errors is to reformat your laptop.
  • OS Upgrade. This is another reason why you must reformat your laptop. Upgrading the operating system of your computer means bringing new features and other crucial specifications to keep your computer at par with the recent market demands. Also, upgrading your computer will install the current versions of the drivers, software, and including chipsets.
  • Your Computer is Performing Slow. If you observe that your computer is running slow, there might be a bigger problem that you need to fix. There are instances that you can boost the performance of your computer through hardware replacement. However, if you can’t do anything about the speed of your computer, better just install a new OS.

Steps in Installing Windows 10 Operating System to Your Laptop


The first step in formatting your laptop is to insert the bootable flash drive/CD installer in the system unit.

  • Access the Basic Input Output System (BIOS) of the computer by continuously pressing F2/delete (other brands is F10) keys until the BIOS tab appears.
  • Then, go to the ‘advanced BIOS’ configuration options and navigate to the boot options. Set the Windows 10 installer (could be a bootable flash drive or CD) as the first boot, and the Hard Disk Drive as the second boot. Press F10 to save changes and reboot. As the computer restarts, make sure to press any keys to load the installer.
  • Now, you can set the operating system preferences such as the language, time and country, and input or keyboard method. Then, click ‘install.’ You will be then asked for a product key, but if you prefer to activate it later, you can skip this process.
  • Accept the license terms by checking the prompt box then click next.
  • If you want to upgrade the old operating system, you can proceed with the ‘upgrade’ installation, but if you want a clean install, you must click the ‘custom’ installation preference.
  • The next to appear on screen is the existing HDD partitions. Since you want to take a clean installation, you need to delete all the existing partitions. Before doing this step, make sure to have a backup file of the important data of your laptop.
  • Then, you can configure the storage capacity of the drive C (partition 2), and you can also add another volume as drive D (partition 3). Take note that as a default, there will be an automatic creation of partition 1 for system reserved.
  • After creating the intended partitions, you need to format all the partitions, so that as the computer reboots all of its drives (including the newly-created drive D), it will have a file system.
  • When you are done setting all the partitions, you can now click ‘next’ to proceed with the installation. Before you continue, make sure that the partition selected is the partition 2 (drive C). Always remember to install the operating system only in drive C. Just wait until all the OS files are installed to your computer, including Windows features and updates.
  • To continue the installation, a restart is necessary. Once the computer completely turns out its display, you need to remove the installation flash drive or CD. This is to allow the reformatsecond boot option (which is the HDD) to take over and complete the installation process.
  • The computer will boot from its HDD and will continue the installation of the Windows 10 OS. Then, you have to enter the product key (or if you are a technician you can just leave it blank and do the activation ‘magic’ later on).
  • Another window will flash regarding on the sending of error and diagnostic reports to Microsoft, just select ‘use express settings.’ Then comes the personalization configuration, like asking if the computer belongs to an organization or just for personal use.
  • The next step will require you to input your Microsoft account (if you don’t have one, you can create it in this phase) and link it to your computer. This is another built-in security scheme of the Windows 10. However, if you plan to connect your Microsoft account later, you can press ‘skip this step.’
  • You’ll be asked about the PC name and password. If you don’t want to put a password leave it blank.
  • Then, wait for the finishing touches, and enjoy the difference only Windows 10 OS can provide you.
