    Run Startup Repair in Windows 10
    Boot to Advanced Startup Options in Windows 10

    When a startup repair fails it may or may not create a file.
    The image on the display typically indicates whether it was created for the current repair.
    There may be a text file from a prior automatic repair.

    type: copy c:\windows\system32\logfiles\srt\srttrail.txt X:

    (replace X: with drive letter assign to USB flash Drive)

    To see which drive letter assign to USB flash drive:
    type: diskpart
    type: list volume
    type: exit

    To search manually: boot windows Recovery Environment (RE) > command prompt > type: notepad > on notepad click file > open > search for:
    C:\Windows\System32\Logfiles\Srt\SrtTrail.txt
    %windir%\System32\LogFiles\Srt\Srttrail.txt

    I deleted the F: partition. The computer rebooted OK.

    I moved the D: and E: partitions into the new unallocated space. I then rebooted.

    I would get rid of that extended partition if you don`t have anything on it. Delete it to unallocated space.

    Try startup repair again.

    If you can get windows to boot again, please label your drives properly

    I notice you have a system reserved partition on the drive, but it is not being used to boot from as the C: drive is marked as active and system. I wonder is making the system reserved partition the actual system partition the computer boots from would help.

    The question still to be resolved is why is repartitioning the drive breaking the Windows 10 boot?

    Fix Windows 10 boot via command line

    The computer boots again.

    My whole purpose of doing this is to remove partitions D:, E:, and F: and just have one partition C: on the boot drive. Partitions D: and E: have programs installed on them so I can't just delete them. This is especially true for games because in the past I have had some of them no longer activate when reinstalled too many times.

    My next step is to start uninstalling programs on the D: and E: partitions. Once done I can delete these partitions. I can then take the next step and extend C: to fill the whole drive. I can then reinstall the programs that were previously removed. The final step is to bring back the data from the deleted F: partition. This will restored from my external backup drive.

    NavyLCDR is on the mark for system reserved.

    The system reserved is supposed to be displayed in disk management as:
    System
    Active
    Primary

    On your computer C: is displaying:
    Active
    System






    These are some disk management, mini tool, and diskpart comparisons:

    • 2011 Clean Install of Windows 7 Ultimate 32-bit
    • 2013 Clean Install of Windows 7 Ultimate 64-bit
    • 2020 Free upgrade to Windows 10 Professional 64-bit

    As you can see these partitions were created by Windows a long time ago. What changes do you suggest I make?

    BTW, one of the changes suggested earlier was to update my BIOS. I was perplexed by this. Here are notes I found:

    • Thursday April 25, 2013: Replace F8 BIOS with F9 BIOS
    • Thursday February 27, 2014: Replace F6 BIOS with F9 BIOS

    It is apparent that unknown to me the BIOS has been rolled back at least three times by Gigabyte Dual-BIOS.
