Desktop Mini HP Pavilion recovery steps

[ateodoro]

My Desktop Mini HP Pavilion - 300-030nl doesn't work anymore. The Window 10 Pro probably was corrupted by the las Windows update. I have no recovery point beacause I've never done it. I've tried to reinstall Window 10 many times following the using Microsoft Window official site instructions: I've made an USB installation disk using the ocfficial tool but no results. Everytime the intallation is blocked after all is installed and the PC is in an infinitive start loop.

Many thanke in advance

This issue is often due to a failing drive. So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive 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.
