Welcome to the Forums.
If using another drive works fine on the G510 then I suspect that the stock HDD is failing or has corrupt partitions.
Can you consider using a 2.5" SATA enclosure to convert the stock HDD into an external drive and try to format the drive and/or run a hardware scan on it using the following:
- Lenovo Storage Test or
- HD Tune.
When finished, try to insert it back on the G510 and observe.
If you get errors on the scan or if the above step is not possible, I recommend you contact warranty support on how to go about getting the unit serviced.
