If not, to check the HDD you have to follow these steps: 1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over. 2) Eventually, you will see an HP Startup Menu 3) Press the Function key for testing the hard drive (usually F2) and let it run.
If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.
Please note that if your model has an SSD instead of an HDD, these diagnostics might not work properly.
