How Can I Install Windows 10 on a Fresh PC Without OS?

My old computer is broken, so I bought a new one yesterday. But I know little about computers. I am aware that the first step is to install Windows. But how to install Windows 10 on a fresh PC without OS? Thanks in advance!

To install Windows 10 on a new PC without an operating system, you need a bootable USB drive or DVD as installation media.

The installation media must contain complete Windows 10 setup files to complete the OS installation process. EaseUS Todo Backup can help you create a bootable USB drive or DVD. If you plan to use USB as the installation media, it is worth mentioning that the USB should at least have 8GB of storage capacity.

Once you properly created a bootable media, here is the detailed guide about installing Windows 10 on a fresh PC without OS:

Step 1. Connect the bootable USB or DVD to your new PC, then restart the computer.

Step 2. Press the corresponding key to access the BIOS or UEFI firmware settings. (Depending on the different computer, the key presses to enter the BIOS or UEFI may vary.)

Step 3. Find the boot order or boot priority settings, then set the USB drive or DVD drive as the priority to boot.

Step 4. Save the modifications and exit the BIOS or UEFI settings. Restart the PC to boot from the installation media.

Step 5. The directions that appear on the screen will guide you to install Windows 10. Then, it will guide you through configuring initial settings like region/language, user account, terms of use, etc.

Step 6. Once the setup is done, you will see the computer reboot and the first-time installation process.

Note: Make sure you have enough unallocated space for creating partitions after Windows is installed.

You can install Windows 10 on a fresh PC without OS. But you have to use a bootable USB drive creator tool to create the installation media to do so.

If it's still confusing for you after reading this post, you'd better check the user manual or the manufacturer's website for more detailed instructions. Below is an article about how to create a bootable USB drive. Click the following link to read more:
