Ready to Install Windows 11 on Your New PC?

What You’ll Need

Before you begin, make sure you have the following:

A USB drive with at least 8GB of storage.
A stable internet connection (for downloading the Windows 11 ISO and creating the bootable USB).
Access to another computer to create the bootable USB drive.
Your Windows 11 product key (if you have one).
A compatible PC that meets the minimum system requirements for Windows 11.

Creating a Bootable USB Drive

Download the Windows 11 Media Creation Tool from the official Microsoft website.
Run the Media Creation Tool.
Accept the license terms.
Select “Create installation media (USB flash drive, DVD, or ISO file) for another PC” and click “Next.”
Choose the language, edition (Windows 11), and architecture (64-bit). Click “Next.”
Select “USB flash drive” as the media to use. Click “Next.”
Select your USB drive from the list. Click “Next.”
The Media Creation Tool will now download Windows 11 and create the bootable USB drive. This process may take some time.
Once the process is complete, click “Finish.”

Booting From The USB Drive

Insert the bootable USB drive into your new PC.
Turn on the PC.
During startup, press the appropriate key to enter the BIOS/UEFI setup. This key varies depending on your motherboard manufacturer (common keys include Delete, F2, F12, or Esc).
In the BIOS/UEFI setup, navigate to the “Boot” menu.
Change the boot order to prioritize the USB drive.
Save the changes and exit the BIOS/UEFI setup. Your PC will restart and boot from the USB drive.

Installing Windows 11

The Windows Setup screen will appear. Choose your language, time and currency format, and keyboard or input method. Click “Next.”
Click “Install now.”
If you have a product key, enter it here. If not, you can select “I don’t have a product key” and enter it later.
Select the version of Windows 11 you want to install. Click “Next.”
Accept the license terms. Click “Next.”
Choose the installation type: “Custom: Install Windows only (advanced).”
Select the drive where you want to install Windows 11. If it’s a new drive, it will likely be unallocated space.

If you have multiple drives or partitions, select the one you want to use.
If you want to create partitions, click “New” and specify the size of each partition.

Click “Next.” Windows 11 will now be installed on your PC. This process may take some time, and your PC will restart several times.
Once the installation is complete, Windows 11 will boot up and guide you through the initial setup process.

Completing the Setup

Select your region and keyboard layout.
Connect to a network.
Choose whether to set up for personal use or organization.
Sign in with your Microsoft account or create a new one.
Create a PIN.
Configure privacy settings.
Choose your desired customization options.
Windows 11 will finalize the setup process, and you’ll be taken to the desktop.

Tips

Ensure your BIOS is up to date before beginning the installation process.
Back up any important data before installing Windows 11.
If you encounter any errors during the installation process, consult the Microsoft support website or online forums for assistance.
Download and install the latest drivers for your hardware after installing Windows 11.
