Welcome Joshua Kennedy,
Thank you for reaching out to Microsoft Q&A forum.
I understand you are trying to change from Windows to Atlas OS and are having difficulty with the step related to disabling Windows security during the installation process.
To make sure I am aligned correctly before going further, I need to narrow this down a bit:
- Are you currently using Windows 10 or Windows 11 Home on this device?
- Are you following an official Atlas OS guide or script, or a community video/tutorial?
Looking forward to your response.
