Part 2: How to Fix Windows 10 Errors in WinRE

Under WinRE, we can use different tools to maintain, restore, reset and reinstall the system to fix errors on Windows 10, without any third-party tool. Besides, WinRE can be installed into the other media. Then, this media (hard disk/USB/disc) can be the Windows boot media to recover the faulty system.
If Windows OS is unbootable or damaged, you should confirm the causes and then select the recovery tools. For example, the disk is damaged; the system file is corrupted or lost; the system update is hold. Here are the steps about how to operate under WinRE.
How to enter into WinRE:

● Press the power button when the Windows logo appears. Repeat this action three times. Soon, the system will enter into WinRE.

● From the login screen, click Shutdown, then hold down the Shift key while selecting [Restart].

● In Windows 10, select [Start] > [Settings] > [Update & security] > [Recovery] > under [Advanced Startup], click [Restart now].

● Boot to the recovery media when you’ve made.

After following one of the above methods, the computer gets into WinRE. You can click on [Troubleshoot] to select the advanced options to fix the system. Next, we will introduce 5 methods about how to use these options to fix errors on Windows 10.

System restore has been used in Windows XP. We can use a restore point recorded on PC to restore Windows. Each time when you install new apps and drivers, a new restore point will be generated. Of course, you can manually create a new point. The individual files will be affected when you restore Windows through such method. But those posterior to the point, such as the applications, drivers and the update package will be emptied.
