Error message appears when Windows fails to detect the installation.
I recently purchased a new NVMe SSD intending to run Windows 11. After installation, I tried booting from the drive but it didn’t locate the Windows installation. It prompts me to "Reboot and select proper boot device." The drive appears recognized both in Windows and BIOS, which suggests something is installed—since I have another SSD with Windows files on this new drive. The drive is GPT-formatted and BIOS is set to UEFI with Secure Boot enabled. NVMe Drive: WD Black SN750 1TB Motherboard: ROG STRIX B450-F GAMING I’m happy to provide further details if needed (English isn’t my native language).
