1, please recall whether you have done any special operations recently and this phenomenon has occurred? For example, have you made any hardware changes (such as adding new memory)? If so, I suggest you try to restore the previous hardware configuration. If external devices are connected, you can try to disconnect all external devices.
2. If you haven't done any special hardware operation, please press F8 to see if there is an option of "Select the last correct configuration" or "Safe mode". If you can see "Choose to use the last known good configuration", please select it to see if it enters the system normally. If you can't get into the system, try entering Safe Mode. If this happens after you install a software or make a setting, you can uninstall a previously installed software or try to restore the previous setting.
3. If it doesn't work well, I suggest you check the hard disk in the BIOS to determine whether it is faulty. Detection method: Press F2 to enter the detection interface after booting, and then select hard disk test (or HDD self-test) to detect the hard disk. The whole process takes about 30 to 60 minutes. Remind you to connect the battery and the power adapter for power supply at the same time during the test.
(1) If there are no errors in the hard disk detection process and all the results pass, then your hard disk should be fine. This situation is probably a system problem. It is suggested that you can try to reinstall the operating system or restore the system after saving the data.
(2) If there is an ERROR on the screen, such as error or FAIL, there is something wrong with the hard disk. Please send the laptop to the nearest HP Gold Service Center for processing. You can check the nearest HP Gold Service Center on the following website:/zh/support-drivers/eSupport/ascpps.html.
