During recent power interruptions at school, my computer experienced strange behavior. When booting from UEFI it would display the UEFI interface but then shut down abruptly with fans increasing. My Windows installation also became unstable. Recently I tried to resolve the issue by installing the latest updates and everything worked smoothly. However, when I tried to power on from sleep, it returned to the UEFI screen and then crashed. I reached out to my older brother for assistance since he was home from college. He booted into UEFI and found the system restored to default settings. He thought the black screen resulted from a corrupted boot manager that only allowed booting from my Samsung SSD, which then reported it couldn’t find an OS. He reset the boot options back to their original state but the problem persisted. We attempted to force boot on all drives and listed partitions, but Windows failed to detect any installation. The UEFI screen appeared repeatedly with the message “An operating system wasn't found.” What should I do? I have the following hardware: ASRock B450M PRO 4 motherboard, Gigabyte OC 6G GTX1660 Super, 16GB DDR4 3200MHz RAM, 512GB Samsung 970 EVO, a 240GB SanDisk SSD (previously used for Windows), and a 1TB HDD intended for games that might contain a Windows backup.

It's likely the sudden power drop or surge damaged system files. You might attempt to start a command prompt, then run scandisk /n on the C: drive to check for issues. Clearing the CMOS is also recommended since it holds system files between reboots.

I wouldn't be able to run the command prompt because the system doesn't appear to have an operating system installed. I'll look into whether resetting the CMOS could help.

During the fresh Windows setup, did you disconnect the other two drives? Typically, when you encounter an error saying no OS is installed, it means the location was incorrect. Also, don’t assume your power supply will always work nonstop. A brief outage can cause problems. Even a basic UPS helps prevent this. Perform a health check on the Samsung EVO SSD to confirm it’s functioning properly. I’ve used Samsung SSDs for many years and they’ve been dependable, though you never know when one might fail.
