How To Install Windows On A Laptop Without Operating System

Some of us might be dealing with a second hand or a hand me down laptop or a brand new purchased laptop with no OS on it. How do you go forward? This tutorial will show you how to install Windows on a laptop without an operating system.

1. You will need a functional computer in order to create a bootable USB installer for Windows. You can follow through this tutorial on how to make a bootable USB installer for Windows.

2. Armed with your bootable USB installer for Windows, plug it into an available USB 2.0 port. If you have no USB 2.0 ports on your laptop, a USB3.0 will do.

3. Power up your laptop.


4. While powering up, depending on your laptop, you should tap either the ESC or F2 or F8 or F10 or Del key in order to get into BIOS. You can skip to step 8 if you know which key brings up the boot order for your laptop instead of having to sift through BIOS. If you do find the key to select your boot device order/options, selecting the device you want as primary boot will remain that option until the next boot up.

5. Upon entering BIOS you will need to look through your bootable device options and the order in which they’re in. This should be found in the advanced or Boot section towards the end of the listed tabs. You may even need to enable an option whereby BIOS will see your USB drive as a removable disk/CD.

6. Choose to have your USB drive as the primary booting device.

7. Move to Exit, save settings and then wait for the laptop to reboot with the new settings.

8. You should be greeted with a screen allowing to choose your language of installation, the time and currency format as well as the keyboard or input method. This is known as the Setup Screen.

9. Click on Next.


10. Click on Install Now.


11. Input your activation key in the space next to the keyboard icon. If you don’t own an activation key, you can click on I don’t have a product key.


12. Choose “Custom: Install Windows Only” to perform a clean install. Please be forewarned that this action will tell the installer to remove everything on the drive you wish to install (following up).


13. Choose the partition/drive you want to install your OS. You should be able to identify the drive you want to install on after you inspect the Total size of the drive in question.

14. Click on Next.

15. You should now see a screen whereby the OS has begun installation. This process should take about a few minutes to about an hour depending on if you’ve got an SSD or and HDD or an SSHD on your laptop.


16. When the installation initiates a reboot for your laptop, go back into BIOS and check to see what the primary boot device is. Ideally it should be Windows Boot Manager.

You should see this screen after your installation is complete.


And with that, happy computing with your new Windows installation on your laptop.
