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.
