    I Just downloaded the windows ico and was able to boot into windows recovery, so that is exciting! There are a few options such as startup repair and system restore, however they can't find any issues nor find a copy of windows to resort to. I can now access the command prompt, however, it says,
    "Microsoft Windows [version 10.0.17134.112]
    Not enough memory resources are available to process this command.

    I entered the script that you gave me reply before and its results are belowClick image for larger version.

    What are the answers to the questions in the prior post?

    3) Had you backed up files?
    4) Had you made a backup image?
    5) If you had to would you be able to make a clean install?
    6) What is the status of the drive?
    7) Had there been any drive tests?
    8) Are all parts original or had hardware been replaced?

    The commands in post #8 are when Windows has a normal boot and administrative command prompt or administrative powershell is used.
    Currently the computer was not able to boot normally.
    When using the Windows 10 iso this is Windows Recovery Environment RE and the commands are different.
    In windows recovery when you click on command prompt it will open a black box with title bar: Administrator: X:\windows\system32\cmd.exe
    There will be a prompt: X:\sources>

    The steps that you made early on were reported but there were no images in the thread. Many times when startup repair is ran there is a prompt about srttrail.txt. Did you see this? If not it will be part of the troubleshooting steps to see if it is an options.
    For all these steps please post images of the commands and the results. The steps listed are commands to type and any comments will be in parenthesis.

    First see if you can open the Windows advanced recovery on the computer without using the Windows 10 iso.
    Power on the computer and as soon as you see the Microsoft windows icon power off.
    Power on again and as soon as you see the Microsoft Windows icon power off.
    Power on the third time and this time allow the computer to progress to the Windows advanced troubleshooting menu. This typically includes the message "diagnosing your PC"
    If it does not progress to the computer's windows advanced troubleshooting menu you will then use the Windows 10 iso.
    There are more troubleshooting options with the computer's windows advanced troubleshooting menu if you are able to open it.

    Find two flash drives ( > or = 8 GB) that you can format that are in addition to the Windows 10 iso flash drive.

    These are the steps for the Windows 10 iso:

    1) Insert the Windows 10 iso flash drive into any USB port
    2) Power on the computer and click the applicable keyboard key.
    List of PC brands with their corresponding hot-keys
    If there is no applicable keyboard key or if the step does not work then temporarily modify the BIOS boot order so that you can boot to the external USB hard drive
    3) It may take 5 - 10 minutes for the iso to load while viewing the Microsoft Windows icon
    4) Select the language, time, currency and keyboard or click next
    5) In the left lower corner click repair your computer (do not click install)
    6) Click troubleshoot
    7) Click system restore (start with the oldest system restore point and keep repeating as necessary to the most recent restore point) ( if system restore fails or if there are no restore points move to the next step)
    8) Click startup repair (if it fails it may post a message that it has created a srttrail.txt) (if you see this message make a note in the thread) (if startup repair fails move to the next step)
    9) Click on command prompt
    (this should open a black box with title bar: Administrator: X:\Windows\system32\cmd.exe and prompt: X:\Sources>)
    10) (type all of these commands) (comments will be in parenthesis)
    (Take pictures of all of these steps and post images of the commands and results into the thread)
    11) bcdedit /enum
    12) bcdedit | find "osdevice"
    13) C:
    14) dir
    15) D:
    16) dir
    17) E:
    18) dir
    19) X:
    20) DISM /image:G:\ /cleanup-image /revertpendingactions (change G to the partition letter displayed in step #12)
    21) (reboot and open command prompt > Administrator: X:\Windows\System32\cmd.exe > X:\sources>)
    22) chkdsk /r G: (change the letter G to the letter displayed in step #12) (this may take many hours and typically displays ETA)
    (reboot as necessary)
    23) (reopen command prompt > Administrator: X:\Windows\System32\cmd.exe > X:\sources>)
    24) (Insert another flash drive into any USB port so that you can save files to the USB drive and move the files to another computer and then post into the thread)
    25) diskpart
    26) list disk
    27) list volume
    28) select disk 0
    29) detail disk
    30) list partition
    31) select partition 1
    32) detail partition
    33) select partition 2
    34) detail partition
    35) select partition 3
    36) detail partition
    37) select partition 4
    38) detail partition
    39) (if there are more partitions then continue in the same fashion)
    40) select disk 1
    41) detail disk
    42) list partition
    43) select disk 2
    44) detail disk
    45) list partition
    46) exit
    47) copy c:/windows/system32/logfiles/srt/srttrail.txt Q: replace Q: with drive letter assigned to the blank USB flash Drive)
    48) (if there is any problem running this command then type: notepad)
    (when notepad opens click file > open > search for srttrail.txt or windows/system32\logfiles/srt/srttrail.txt) (save to the flash drive then move to the working computer and post into the thread)
    49) sfc /scannow /offbootdir=c:\ /offwindir=c:\windows (change the letter c to the letter for the partition seen in step #12)
    50) bootrec /fixmbr
    51) bootrec /fixboot
    52) bootrec /scanos
    53) bootrec /rebuildbcd
    54) (reboot)
    55) (more steps to follow depending up the above results)
    (please make sure that images of all commands and results are posted into the thread)

    Sorry I wrote out the answers before I tried the windows ISO but accidentally deleted them.
    3-4) I Haven't backed up anything
    5) I don't have much on my drive so I wouldn't mind losing everything on it
    6-7) I did tests on the harddrive through BIOS and it didn't find any issues. passed all tests.
    8) The laptop itself is refurbished, and I did replace the hard drive a few months ago when there were some issues with the computer freezing due to the operating system.

    I ran all the steps you gave and will list the results below. When I finished, it asked "add installation to boot list?" when it identified one windows installation. It gives the option of Yes and No, but I'm not sure what I need to do, so I'm just going to have my laptop plugged in and running for the time being.Click image for larger version.

    Laptop commands - Google Drive

    I couldn't find another flash drive, so I just saved the text file to the external drive with windows on it. I don't know if this is an issue or not, but I won't be able to send until I can connect the external drive. I looked through the file and it showed 0 errors.

    I would like to note that step 20 comes up with no files. Perhaps this could be the source of the issues?

    Review these links to see whether there were any typos or errors:

    How to Rebuild the BCD in Windows
    Fix: bootrec /fixboot access denied in Windows 10
    How to Fix Windows 10 Startup Problem - YouTube

    If there were no typos or errors there are additional steps that will need flash drives that you can format.

    re no#9 above .................the EFI folder is likely in the 2nd volume you assigned the drive letter Q too , not on C: perhaps ? not sure if bootrec.exe is in there though...
