Acer Nitro 5 AN515 'No Bootable Device' Error on Windows 11


I recently bought an Acer Nitro 5 AN515 NH.QM0EY.009 laptop with Windows 11 pre-installed (not FreeDOS), and after just two months, I encountered a “No Bootable Device” error. Despite my attempts to troubleshoot using online videos, I found that the BIOS menu lacks a “Legacy” option under the boot settings, leaving me with no clear solution.
This situation is incredibly frustrating for such a new device. Acer, I need urgent assistance to resolve this issue. I didn’t expect to face such a major problem so soon, and I’d appreciate clear guidance on restoring functionality to my laptop without further delays.
