The simplest way to install a Windows operating system without making a startup disk

The first few steps of the online and well-known way to reinstall the Windows operating system are usually to make a USB drive boot disk or disc boot disk, and install the operating system completely after restarting the calculation. This is a hassle for users who do not have a USB flash drive or CD, no optical drive, and want to install a new Windows operating system (that is, you don't want to install it after starting Windows), so this article provides an easy way to install a Windows operating system without having to make a startup disk.

This method applies to one or more of the following situations:

1. Removable hard disk without USB drive

2. No disc or optical drive

3 a disc but the optical drive does not support burning

4.U disk or USB removable hard drive does not boot or cannot be made into boot disk

5.U disk or USB removable hard drive cannot be formatted

6. New installation of Windows operating system

7. Do not want to install Windows in Windows System

This method requires the computer to conform to any of the following except the 1th:

1. The original system must be Windows7 or above the operating system (Windows Recovery Environment, Windows RE (Recovery environment) is the function after Windows7, refer to the method below the principle)

2.Windows can start normally

3.Windows Although it does not start properly but can enter the repair mode (if the original user has password protection, the user's password is required)

4. There are multiple partitions on the computer, if there is only one system partition (that is, the commonly said C disk) or only one system boot partition (that is, the commonly said 100MB partition or 1000MB partition) and the system partition, you need to use USB drive or USB removable hard disk

Method principle:

Take advantage of Windows Repair mode (Windows7 operating system: Press "F8" on startup)-Turn on Windows ' advanced startup Options ' and select ' Repair computer ' with the up and down arrows Enter any entry to determine the selection) execute Windows Setup on any device that is recognized by Windows to perform the installation of Windows tasks.

Windows Repair mode, also known as Windows Recovery Environment, Windows RE (Recovery Environment), similar to Windows PE (Preinstall Environment), Windows Recovery Environment ( Windows RE) is a recovery environment that fixes common problems that do not start the operating system. Windows RE is built on the Windows pre-installation environment (Windows PE) and can be customized with additional drivers, languages, Windows PE optional components, and other troubleshooting and diagnostic tools.

Windows Recovery Environment (Windows RE) is a scalable recovery platform based on Windows pre-installation environment (Windows PE). Windows automatically fails over to this environment when the computer fails to start, and the Startup Repair tool in Windows RE automatically diagnoses and repairs Windows installations that cannot be started. In addition, Windows RE is a starting point for a variety of manual system recovery tools.

Windows 8/8.1/10 to the Windows Recovery Environment in the same way that you can query for yourself.

A Hands-on demo (here with Windows Server R2 as an example, the Windows7 operation is the same, the following part of the picture is for demonstration purposes only, don't be too serious):
