Welcome to the Forums.
It seems like you have a bad HDD. If you have a spare USB flashdrive, can you create a UEFI Bootable Diagnostic and run a scan on the HDD to verify its health.
If the above steps are not feasible then I recommend you contact lenovo or a local computer repair center for service.
