Two Ways to Install Windows on a New Computer Without an Operating System

Installing Windows on a brand-new PC with no operating system is a lot more complicated than reinstalling Windows on one that already has it. But it can be done. Let's take a look at how.

Method 1: Perform a System Restore

Have you heard of Universal Restore? It allows you to create a Windows system image on an external hard drive and restore the system image backup to a different computer without compatibility issues. However, for this, you'll need to use professional universal recovery software like AOMEI Backupper. Such a tool can help you easily install Windows on a new PC.

Todo Backup Home is a powerful backup and recovery tool for Windows PCs. It enables you to perform a universal restore on different hardware to deploy your Windows system. For instance, you can use it to transfer Windows from one computer to another hassle-free.

It also lets you automate the backup of your system, disks, files, apps, and more, and create a Windows 11 system image on a USB drive to be ready in case of a system crash.

Some of the main features of Todo Backup Home include:

With Todo Backup Home, you can fulfill all these requirements, whether it's for backup or general recovery. Download and install it on your computer to prepare for installing Windows 11 on your new PC.

Here are the steps to install Windows 11 on a brand new computer without an operating system:

Step 1. Create an Emergency Disk on a USB/External Drive

Step 1. Get a USB drive that you can write to.

Step 2. Launch and install Todo Backup on computer B.

Step 3: Click on "Tools", and then choose "Create Emergency Disk".

Step 4. Choose where you want to save the bootable disk. You can create an ISO file, or a bootable USB or CD/DVD.

Step 5: Click Create to get started.

Step Two: Create a system-image backup of the source computer

Step 1. On the main screen, tap "Select Backup Content".

Step 2. Click on the Operating System category from the four available options.

Step 3. Todo Backup will automatically select your system partition. You just need to choose a backup destination.

Step 4. You can choose to save the backup file on your local disk or NAS.

5. After the backup process is complete, you can check the backup status, recover, open, or delete a backup by right-clicking the backup task on the left.

Stage 3: Boot the target computer from the emergency disk

Step 1. Eject the emergency disk and system backup USB/external drive, and connect it to the new computer.

Step 2. Restart your computer and press DEL, F2, F10, or F12 to enter the BIOS.

Step Three: Boot into the boot menu and configure the new computer to boot from the Tools emergency disk.

If you want to restore system image to GPT disk, you need to change the boot mode to UEFI in BIOS. Then, your computer will enter the main interface of Todo Backup.

Here are some articles about different laptop boot menus.

Stage 4: Restoring the System Image to a New, Bare Metal Computer

If you are unable to boot the computer, try to start it from a Todo Backup WinPE bootable disk to perform system recovery.

Step 1. Launch Todo Backup and click on "Browse Recovery".

Step 2. Navigate to your backup destination and select the system backup file you need. (The backup files created by AOMEI Todo Backup are with .pbd extension.)

Step 3. Select the recovery disk. Make sure that the partition style of the source disk and the recovery disk is the same.

4. Customize the disk layout as needed, and then click Continue to begin the system restore.

5. Boot the migrated system on the new computer

Finally, you'll need to set the BIOS on the new computer to boot from the hard drive, just as the old one did.

Step 1. Restart your computer and press F2/F8/Del to enter the BIOS.

**Step Two.** Go to the Boot menu and find the BIOS mode.

Step 3: Set the Boot Mode to match what your original computer used: either Legacy BIOS boot or UEFI boot.

4. Save the changes and exit, allowing your computer to restart.

You can also use Todo Backup to perform disk cloning for system migration. With cloning, you can easily transfer Windows from one computer to a new PC. You won't need to install the OS, set up Windows 11, or reinstall apps. What you need to do is remove the internal hard drive from the new PC and connect it to the old PC running Windows 11.

However, note that this method can run into compatibility issues, so a full restore is preferable.

Method 2: Clean Install Windows 11

If your new computer doesn't have an operating system, you can also perform a clean install of Windows 11. To do this, you'll need to create a Windows installation media, such as a bootable USB. Here's how:

First, create a Windows 11 installation media.

To install Windows 11 on a brand new computer without an operating system using a USB, you first need to create a Windows 11 installation media. You can use tools like the Windows Media Creation Tool, Rufus, or OS2Go to create a bootable USB drive.

To create a bootable USB drive using Rufus or the Media Creation Tool, you'll need to download a Windows 11 ISO file from Microsoft's website. You'll also need to download the Media Creation Tool on the new computer.

Here's an article on how to create a bootable USB drive.

**Step Two: Boot the new computer from the USB drive**

With the Windows 11 bootable USB created, you can use it to start your new computer. Here's how:

**Step 1:** Connect the bootable USB drive to your new computer.

Step two: Start the computer and press a certain key to enter the BIOS setup (a different key may be required for different PC manufacturers, but common ones are F1, F2, F10, F12, Delete, and Esc).

3. In the BIOS (Basic Input/Output System) menu, look for “Boot Options” and set the USB drive as the first priority. The new computer should then boot from the Windows 11 installer.

Step 3: Install Windows 11 on the new computer

After booting the new computer from the USB drive, you can begin the clean install of Windows 11 on your new PC. In short, you need to install Windows 11 and go through the Windows 11 out-of-box experience (OOBE).
