The perfect tutorial to reinstall Win8.1 system

After the Win 8 system, the cumbersome reinstallation of the system process has become so simple and user-friendly.
Because Win8/Win8.1 introduces three new system recovery features. "Restore computer
without affecting your files" (similar to what we think of system repair), "Restore all content and reinstall Windows
” (similar to our often Said system reloading), "advanced startup" (similar to the Win7 era of system recovery)

The following system tribes will take you to learn to use the system reinstallation process under Windows 8.1 system.

Preparation Tools: A copy of the Windows 8.1 ISO system image.

Specific steps:
1. Load the Windows 8.1 ISO image and copy the image/sources/install.wim file to other non-system disk directories, for example: D:\\sources folder.

2. Query the install.wim information in the ISO image. For example: enter the dism query command in the command character (administrator)

dism /get-wiminfo /wimfile:d:\\sources\\install.wim

//can query D:\\sources The system images contained in \\install.wim and their respective index numbers.
For example, the system tribe is a 64-bit Windows 8.1 Enterprise Edition with an index of 1.

3, is also the most important step: configuration recovery image work: then need to use the REAgentC command

//REAgentC.exe tool is for Windows 8/Windows 8.1/Server 2012/Server2012 R2 Supports setting up Windows(R) repair environment (Windows RE) boot image and one-click recovery backup image. It can also be used to manage recovery options and custom projects. The REAgentC command can be executed on an offline Windows image or on an executing Windows operating system.

Start configuring the recovery image

Enter the configuration command in the command character (administrator)

reagentc /setosimage /path X:\\sources /index N

//The path after the path indicates the path to the folder where the install.wim file is located. The N after the index indicates the index number in the wim image to be restored

So the system tribe edits the recipec /setosimage /path d:\\sources /index 1
After the operation is successful, execute the reagentc /info command View the configuration of the recovery image:

4, the preparation work is done, the system recovery (reload) can be started at any time
Open the computer settings, enter the update and recovery, select recovery.

If you plan to transfer your computer to someone else, it is recommended to choose the second option, so that the partition will be erased first in the recovery process so that the original files in the partition are difficult to recover, which will take a long time.
In the last step, after clicking “Initialize”, it will automatically restart to complete the initialization process. If you do not intend to reinstall the system, please be cautious. The initialization process takes about 10 minutes. After the completion, it will restart again. After the restart, some hardware driver configuration, user account settings and other operations are required. After the configuration is complete, you will be taken to a brand new Windows 8.1 operating system
.

Attached: x:\\sources\\install.wim, you can directly use the wim image in the original system installation image, or you can use dism to manually back up the wim image after the complete system disk, eliminating the need to install software and The annoyance of the drive.

After reading all the above steps, do you think that in the era of Win8/Win8.1, system recovery or reinstallation becomes particularly simple.
