    The images that you just posted I cannot read.

    Create a bootable windows 10 iso per post #9
    For Toshiba the boot to device key is the F12 key per this link: List of PC brands with their corresponding hot-keys
    When you boot to the windows 10 iso there will be a windows icon which will take 5 - 10 minutes to load.
    Select the language, currency, time, and keyboard and click next.
    If you click install you will have the option to delete the drive partitions, format the drive, make an unallocated drive, and then be able to install a new windows 10 operating system. This would be a clean install removing all files and applications in addition to the operating system.
    Instead of clicking install look on the lower left for repair.
    Click on repair and open the menu with the Windows recovery or advanced troubleshooting menu.
    Click troubleshooting.
    Click system restore ....if this works you are done.....if it fails go to
    Startup repair................if this works you are done.....if it fails go to
    Command prompt.........from here you will attempt a registry repair
    Let us know your progress

    This is the registry repair method:

    There are videos available on youtube:
    How to Fix Windows 10 Startup Problem - YouTube

    1) boot to the Windows 10 iso
    2) it may take 5 minutes displaying the windows icon
    3) Use the default settings for language, time, currency, and keyboard
    4) click next
    5) In the left lower corner click Repair your computer
    6) click troubleshooting
    7) click startup repair (it is expected to fail)
    8) click system restore (it is expected to fail)
    9) click command prompt
    You should see a pop up with title bar: Administrator: X:\windows\system32\cmd.exe
    This is the registry backup method:
    For each step you must see sizeable file sizes for this to work.
    If you see zeros the method will fail.
    The command: dir
    will be used each step to make sure you are in the proper location and check the size of the files
    10) type: C:
    11) dir
    12) type: D:
    13) dir
    Choose the C: or the D: drive to proceed. It should be the windows drive and not the USB drive.
    For this post I will use C: however you should pick the drive letter that you found that has the windows files on your computer.
    The proper drive will display: perflogs, program files, program files (x86), users, windows, etc
    14) type or copy and paste: cd \windows\system32\config
    It should display: C:\windows\system32\config>
    15) type: dir
    It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.
    All of the file sizes should be sizeable. If it displays zeros then abort.
    Make a new directory and name it backup or something similar.
    16) type: MD backup
    Copy all of the files into this new directory.
    17) type or copy and paste: copy *.* backup
    It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.
    Change the directory to regback
    18) type: cd regback
    It should now display: c:\windows\system32\config\regback>
    19)type: dir
    It should display: default, sam, security, software, system etc
    All of these files must be sizeable. If it displays zeros then abort.
    20) type or copy and paste: copy *.* ..
    It should now display:
    Overwrite ..\default? (yes/no/all):
    21) type: a
    It should now display: sam, security, software, system and that the files were copied.
    22) type: exit
    23) click turn off your PC
    Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.

    If you are successful with the registry repair perform the following steps in order.
    Do not take the success for granted. Backup the software and check the hardware as soon as possible.
    1) download and install Macrium Reflect free and make a backup image of your drive
    2) use HD sentinel to check the status of the drive: Hard Disk Sentinel - HDD health and temperature monitoring
    3) use Sea tools for windows and run SMART, short, and long generic tests on the drive
    4) open administrative command prompt and type or copy and paste these commands
    a) sfc /scannow
    b) dism /online /cleanup-image /restorehealth
    c) chkdsk /scan
    d) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on copy > paste into the thread
    5) create a brand new restore point
    6) open disk management. Expand all of the column headings so that you can see the contents of all of the rows.
    Use the Windows snipping tool to make an image and post in the thread.
    7) open administrative command prompt and type: chkdsk /x /f /r (this will take many hours to run so plan to run it overnight)
