Installing Windows 10 without a USB is a process called "clean installation," which can be done via the internet and your computer’s internal storage. You’ll need a stable internet connection and enough disk space. This method involves downloading the Windows 10 ISO file directly to your computer, creating a virtual drive, and running the setup from there.
How to Install Windows 10 Without USB
If you’re looking to install Windows 10 without the need for a USB drive, follow these straightforward steps. This guide will help you download the Windows 10 ISO file, mount it as a virtual drive, and install the operating system directly from your computer.
Step 1: Download the Windows 10 ISO File
First, download the official Windows 10 ISO file from the Microsoft website.
This file can be quite large, so ensure you have a fast and reliable internet connection. Navigate to the Microsoft Windows 10 download page and choose the correct version for your system.
Step 2: Open the ISO File
Once the ISO file is downloaded, locate it in your Downloads folder and right-click on it.
Select the option to "Mount" the ISO file. This action creates a virtual drive on your computer, allowing you to access the installation files as if they were on a physical disk.
Step 3: Run the Setup File
Next, open the virtual drive that you just created and look for a file named "setup.exe."
Double-click on "setup.exe" to start the Windows 10 installation process. Follow the on-screen instructions, which include choosing your language, time, and keyboard preferences.
Step 4: Choose "Custom" Installation
When prompted, choose the "Custom: Install Windows only (advanced)" option.
This option lets you perform a clean installation, which means all your current data will be erased. Make sure to back up any important files before proceeding.
Step 5: Select the Partition
Select the partition where you want to install Windows 10.
If you have multiple partitions, choose the primary one. You may need to format the partition to ensure it’s clean. Be cautious, as formatting will erase all data on that partition.
Step 6: Complete the Installation
Finally, allow the installation process to complete.
Your computer will restart several times during the installation. After it’s done, follow the setup to personalize your Windows 10 environment, such as setting up your user account and preferences.
After you complete the steps above, your computer will be running a fresh installation of Windows 10. You’ll need to install your drivers and software again, but this method ensures you have a clean slate to start with.
