    HP Laptop Black Screen on boot


    Power on the computer and open the BIOS UEFI diagnostics.
    This may be the F10 key (repetitively click during power on)
    The default UEFI diagnostics are drive and memory.
    If the UEFI diagnostics were downloaded from the HP website then there are substantially more tests including component tests. If there are available then run the extensive testing or if available the loop until failure testing.
    Run this overnight.
    The testing is designed to abort if there is problem found and post a code.
    If the loop until failure is running the next morning then this is typically a good sign as one or more loops should have completed. Then press the escape key to abort the testing.

    There are different versions of the HP UEFI diagnostics.
    Open the website for HP and click on support and drivers > enter the product or serial number or model > select the operating system > view drivers > post a URL or hyperlink into the thread
    The HP UEFI diagnostics can be installed on a flash drive and used for testing:
    HP PC Hardware Diagnostics | HP® Official Site






    Find a flash drive that you can format ( > or = 8 GB)
    Create a bootable windows 10 iso:
    Download Windows 10
    Download Windows 10

    Insert the windows 10 iso flash drive into any USB port
    Power on the computer and boot to the widnows 10 iso clicking the applicable keyboard key.
    List of PC brands with their corresponding hot-keys
    List of PC brands with their corresponding hot-keys
    Alternatively, temporarily modify the BIOS boot order so that the external USB HD is on top.
    It may take 5 - 10 minutes for the iso to load while viewing the Microsoft Windows icon
    Select language, time, currency, and keyboard, or click next
    In the left lower corner click repair your computer (do not click install as this is the method of clean install)

    In the windows 10 troubleshooting menu on the iso start with startup repair.
    It may fail and display that it created a srttrail.txt file
    See if you can save this file to a flash drive and then transfer the flash drive to a working computer to upload into the thread.

    Next click system restore. Start with the oldest system restore point and keep repeating as necessary until there are no more system restore points. If there are no system restore points or if system restore fails advance to the next step.

    Click command prompt
    This should open a black box with title bar: Administrator: X:\windows\system32\cmd.exe and prompt: X:\Sources>

    Find a camera or smart phone camera to take pictures of commands and results. Then post images into the thread.

    These are commands to type. For comments they will be in parenthesis.

    1) bcdedit /enum
    2) bcdedit | find "osdevice"
    3) c:
    4) dir
    5) d:
    6) dir
    7) e:
    8) dir
    9) x:
    10) diskpart
    11) list disk
    12) list volume

    20) select partition 3
    21) detail partition
    22) select partition 4
    23) detail partition
    24) (if there are any additional partitions then continue in the same fashion)
    25) select disk 1
    26) detail disk
    27) list partition
    28) exit
    29) bootrec /fixmbr
    30) bootrec /fixboot
    31) bootrec /scanos
    32) bootrec /rebuildbcd
    33) (reboot and check boot) (if boot fails then reopen command prompt and advanced to next steps)
    34) chkdsk /r P: (change the letter P to the drive letter displayed in step #2 for the partition)
    (this may take many hours and typically displays ETA)
    (reboot as necessary to run the chkdsk command)

    There are additional commands that depend upon the commands and results.
    Please make sure to post images into the thread for additional troubleshooting steps.
