    Check Disk with the Recover/Repair option ("chkdsk <drive> /R") option will take many hours to finish.

    The latest drivers/bios were for windows 7: HP Software and Driver Downloads for HP Printers, Laptops, Desktops and More | HP® Customer Support

    For HP UEFI hardware diagnostics the latest version is 6.5 or 6.6.
    This version requires a windows download and install.

    There is a version for a USB drive.
    And there is a version for a default installation.

    When the chkdsk has completed please run the HP UEFI diagnostics that are already on the computer.
    Power on the computer and repetitively click the F2 key.
    This should open the BIOS.
    If there is an extensive or loop until failure test run this test overnight.
    If there is a problem the test is designed to abort and display an error code.
    If the loop until failure is running the next day press the keyboard escape key to abort the testing.
    View the results in the BIOS UEFI hardware log to confirm the pass test result.

    If the HP UEFI diagnostics on the computer do not exist or have minimal tests find a flash drive that you can format.
    Create a HP UEFI hardware diagnostic flash drive and test the hardware.
    Report the results into the thread.
    HP PC Hardware Diagnostics | HP® Official Site

    Once there is a working operating system download and install the most up to date HP UEFI diagnostics and run a loop until failure test.

    If Chkdsk command going to take 25 hrs then you might as well cancel Chkdsk command as your hard disk drive is probably failing i have run Chkdsk command on 2TB HDD and this is the estimated 3:00:15 time, this hard drive is external and connected to USB 3.0 port.

    Thank you so much for the help. How do I cancel chkdsk, if I stop in middle it won't cause a problem correct? Also I put d drive for checking chkdsk, I should have verified the drive os as suggested. I also want to take the time to thank you fine people, it is so nice if you to help, very grateful.

    You can press Ctrl + C keys at Command Prompt to stop Chkdsk command.

    I'm not sure you can execute below command from Windows RE but lets try it and if you can post a screenshot of the output of the command.


    Code:
    wmic diskdrive get status

    I am working on running the 3 commands boot free gave, bootrec / fix mbr, fix boot, rebuild bcd if I do this after the scan will it mess up the disk, I want to fix it but worst case I want to make sure I can still access my files to backup via a slave drive as backup.

    You can backup your personal files by executing Notepad from Command Prompt. From Notepad click File from menu bar and select Save this will open a File Explorer where you can copy and paste your personal files to connected storage drives.

    There is an additional option that can fix the recent problems with inaccessible boot device and that is to revert pending actions.
    Let us know the outcome of the present commands.

    The drive can be removed from the computer and placed in a drive enclosure or placed into another computer. Then you can run chkdsk /x /f /r to evaluate and fix the drive.

    An additional option is to use a boot rescue drive and test the drive.

    Let us know your progress.
