Hi,
It seems like your HDD is not being detected. Here are some troubleshooting steps that may help.
- First, load into BIOS and check if the HDD is listed or not.
- If the HDD is listed I would suggest reinstalling Windows using a disc.
- But if the HDD is not listed I would suggest to reseat the HDD.
- Turn the laptop completely off, remove the HDD for a second then put it back in then test it again.
- If it will still not work last option would be to replace the HDD itself.
