Unable to boot back to windows and error while installing Manjaro

Hi @ineedserioushelp, and welcome!

  1. Please see [HowTo] post screenshots and links with regards to thee images.
  2. That screen where you have to select between open-source and proprietary drivers is the boot ISO environments. So it doesn’t start from the HDD/SSD, it tries to start the ISO environment, which is usually a USB thumb drive lately.

Further, please see [HowTo] Provide System Information.
