Perform Hard Drive Tests using HP PC Hardware Diagnostics UEFI
If Windows won't start:
- Hold the power button for at least five seconds to turn off the computer.
- Turn on the computer and immediately press esc repeatedly until the menu is displayed, then press the f2 key.
- On the main menu, click "Symptom Tests".
- Select "Hard disk/SSD drive issue", and press Enter.
- If the computer has more than one hard drive, select the drive to test, or choose "Test All Hard Drives".
