Hi Jake,
Thank you for posting your query in Microsoft Community.
I understand that your system is stuck in a loop and unable to boot past the blue screen. In this case, I would suggest you to boot from the installation media and run a Startup repair. Follow the instructions in the following article and create an installation medium:
***Create installation media for******Windows 8.1***
After creating the media, boot the computer from the medium and then try the following method to perform a Startup Repair in Windows 8.1.
- Contact the computer manufacturer to know on how to change the boot order of the computer. You will have to change the boot device to CD/DVD drive and then boot from the Windows 8.1 installation disk.
- In the “Windows Setup” dialog box that appears, set the Time and currency format, Keyboard or input method and the language to install and then click “Next”.
- Click on “Repair your computer” from the lower left corner.
- From the “Choose an option screen”, click on “Troubleshoot”.
- Click “Advanced Options” in the “Troubleshoot” screen.
- In the “Advanced Options” screen, click “Startup Repair”.
- Follow the on-screen instructions to complete the Startup Repair.
Check if you are able to successfully boot the system.
