1. Check for Hard Drive Issues
The last straw here to delete the reset loop for Windows is to search your computer hard drive for physical problems. Here the bootable MiniTool Partition Wizard’s Surface Test feature will check every sector on your drive and report bad sectors on the drive.
- Boot the computer from the bootable media of the MiniTool Partition Wizard. Then pick the whole device disc, and from the action screen, select Surface Test.
- Click Start Now in the pop-up window to begin testing the hard drive. If bad sectors are detected, they will be labeled with red blocks.
You can initiate a disc backup before data loss happens and install Windows on a new drive if there are several bad sectors. But if no bad sectors are identified, and the reboot loop for Windows continues, contact Microsoft for technical assistance.
2. Disable Automatic Restart
- Press F8 constantly while restarting your computer until you get a Windows logo on the screen.
- Now the boot menu settings appears on the computer screen, release F8 and select Safe Mode.
- Go to the Search box and type ‘sysdm.cpl’ when Windows starts in Safe Mode. From the search results, open sysdm.cpl.
- Go to the Advanced tab and select Settings under Start-up and Recovery.
- Here it would help if you unchecked the “Automatically restart” check box. If it’s not already checked, you might also want to check ‘Write an event to the system log.’ Click ‘OK and restart your computer again.
Whenever your computer is stuck in the reboot loop, this is the very first method you need to try. Did this fix your why did my PC restart issue? If Yes, great. If not, let’s make sure the next solutions
3. Make Startup Repair
You can’t enter “Advanced Options” settings where you can correct the issue as Windows keeps restarting. It would help if your computer booted from a USB or DVD in this case. You’ll need the support of Bootable Media for Windows. Go to any Internet-connected PCs and build bootable media using the Media Development Tool. If the Bootable Media is ready, follow the steps listed below.
- Insert the installation disc for Windows, connect the USB media to your PC, and then boot the machine.
- When you are asked to boot from a CD or DVD, press a key.
Tip: If your PC does not immediately find bootable Windows media during the restart process, read any instructions leading to the computer screen’s BIOS configuration settings. Then to alter the boot sequence, go to Boot Order/Boot Options/Boot. To find a CD, DVD, or USB, please follow the directions and use the arrow keys to get it to the top of the list. Lastly, to save the updates, click a key, and exit the BIOS Configuration Utility. Now from the bootable files, your PC will be able to run.
- Pick a language, time, currency, keyboard, or another input method when you see the Windows installation window, and then press ‘Next.’
- Tap Your Screen Repair.
- Pick the computer operating system you wish to patch, and you will be asked to troubleshoot it.
- Follow this direction now: Troubleshoot -> Advanced Options -> Fix Startup.
- Choose a goal and then start diagnosing the system with Windows. Startup Patch can try to address the Windows reboot loop if any error is found.
If the Startup Repair does not resolve the problem, you can go to “Command Prompt” under “Advanced options” and execute this command:
- Enter Bootrec /RebuildBcd and press Enter.
- Windows 10 Exit Command Prompt and restart.
Continue for the next solution if this does not help your computer.
4.Use Windows 10 Boot Loop Automatic Repair
Automatic repair of the Windows 10 boot loop can occur after several boot failures. And from there, you can make any rescue reset loop for Windows 10. Try the following, please:
- Switch the PC off and then turn it up. Click and hold the Power button to switch it off as soon as you see the spinning loading circle.
- Repeat this step several times until the “Preparing Automatic Repair” computer screen is clear.
- You can see the “Diagnosing your PC” screen after the “Automatic Repair” gui. You need to pick “Advanced options” right here.
- Select ‘Troubleshoot’ -> ‘Advanced Alternatives’ where several choices are open.
- Select ‘Command Prompt’ and begin to execute the command lines below:
c dir cd \windows\system32\config MD backup copy *.* backup CD regback dir Copy *.* .. A Exit
Press “Choose an option” when you return to “Continue” and see if the Window continuous reboot terminates. If this did not fix your why did my PC restart issue then try the next one.
5.Check File System
It would help if you had the assistance of a bootable partition manager in this process. MiniTool Partition Wizard Pro is recommended here because it can help you quickly build bootable files. Follow the steps below to search the computer file system until you are on the main interface of the bootable MiniTool Partition Wizard.
- From the system disc, pick a system-specific partition and click ‘Review File System’ from the action screen.

Tip: To get the “Advanced Options” option, you might “Refresh your PC” Your data will maintain this option, but any installed programs will be destroyed.
- Only follow the screen directions from here until the refreshment is done.
Data backup is required if you plan to do the reset. The bootable media created just now by MiniTool Partition Wizard Pro is very helpful here. Before you do that, plan another format and connect it to your device. Then boot the bootable media out of your PC.
- Select the machined disc as the source disc, and from the action screen, select the Copy Disk option.
