How to Remove Windows?

It takes a few steps to remove Windows from your computer, and you should back up your vital data before starting because doing so will delete the Windows installation and all related files. Here is a general instruction on removing Windows:

1. Make a Data Backup:

To start with, make sure to make a backup of any crucial files, papers, pictures, or other material that you intend to save. An external hard drive, online storage, or another backup strategy are all options.

2. Create an installation media for Ubuntu:

A USB device or DVD for installing Ubuntu is required. Installing the official Ubuntu ISO image and applications like Rufus (for Windows) or Ubuntu's built-in Startup Disk Creator, you may make one.

3. Launch Ubuntu from the installation media:

Restart your computer after inserting the DVD or USB disk containing the Ubuntu installation.

To boot from the installation disk, go to the boot menu or BIOS settings (often by pressing F2, F12, or Del during startup).

4. Set up Ubuntu:

Install Ubuntu by following the on-screen directions. If you want to remove Windows and install Ubuntu, choose that choice when you get to the installation type screen. The name of this option is frequently "Erase disk and install Ubuntu" or a phrase to that effect.

5. partitioning

Ubuntu will inquire about partitioning when you are installing. If you have particular needs, you can either choose to let Ubuntu handle partitioning automatically or build custom partitions.

6. Verify any changes:

Read the list of changes before continuing. To make sure that the Windows partition(s) are being erased, you must complete this step.

7. UEFI/BIOS Configuration:

If you intend to install Ubuntu from external media, make sure the UEFI or BIOS settings on your machine are set up to permit booting from a USB or DVD.

8. Secure Boot 

On some PCs, Secure Boot is turned on by default. Secure Boot is supported by Ubuntu, however you might need to set it up correctly during installation.

9. Considerations for Dual Boot:

Research and abide by dual boot configuration recommendations if you intend to dual boot Ubuntu and another operating system, such as Windows, to prevent any problems.

10. Happy Ubuntu!

You can start using your new Linux-based operating system once Ubuntu has been installed and your data has been restored.

Keep in mind that uninstalling Windows is a one-way operation; unless you have a backup of your Windows installation, you won't be able to recover it. Also take into account any programs or tools you use often. You could require Linux substitutes or workarounds to run Windows programs on Ubuntu by using compatibility layers like Wine or virtualisation tools like VirtualBox.
