Explanation
The 'No Operating System Found' error, combined with the fact that it only appears when the new drive is connected, strongly indicates that the BIOS/UEFI is attempting to boot from the newly installed (empty, unformatted) drive instead of the original drive containing the OS. Checking and correcting the boot order in BIOS/UEFI to prioritize the original OS drive will resolve the issue without any data loss or additional steps. Booting into safe mode is not possible since no OS is found. Formatting the new drive is premature and doesn't address the root cause. Windows Recovery and chkdsk are OS-level tools that cannot run if the system won't boot. Boot order is always the first thing to verify when a newly added drive causes boot failures.
