Step 7: Select the drive for Windows installation. Usually, your computer will have multiple drives (the drive for Windows installation will be labeled as System in the Type column). Since I'm installing on a virtual machine, there's only one drive. Choose the drive, press Format to erase existing data, and finally, click Next.

Step 8: The Windows installation process begins. Wait for about 10-15 minutes, depending on your computer's speed.

Step 9: After the installation is complete, the computer will restart automatically. Wait for a few more minutes. When the computer boots to the screen below, select your country and press Yes.

Step 10: Choose your keyboard language and press Yes.

Step 11: Press Skip.

Step 12: Choose Set up for personal use and then click Next.

Step 13: At this step, if you have a Microsoft account, enter it in the provided space and click Next. If not, select Offline account. It's recommended to choose Offline account as you can add a Microsoft account later after the Windows installation.

Step 14: Click Yes.

Step 15: Enter the computer name in the blank space and click Next.

Step 16: If you want to set a password for your computer, enter it in the blank space and click Next. If you don't want to set a password, leave it blank and click Next.

Step 17: At this point, Windows asks if you want to use the virtual assistant Cortana. Since I don't use it, choose No.

Step 18: At this step, you can turn off all the options and click Accept.

Step 19: Wait a few minutes to complete the Windows installation process.

Now, we have successfully installed Windows 10, and the computer has booted into the Desktop screen.
