    It seems you now believe the Windows partition to be potentially intact.

    One way you could try recovering that is:
    a. created a disk image of that partition e.g. using Macrium Reflect
    b. on whichever disk you care to use- could try a spare one if you have one - clean install Win 10.
    c. check that boots ok
    d. restore the image of Win 10 you created earlier to the new Windows partition
    e. reboot - automatic repair may resolve things
    f. if not, run Startup repair, booting your PC from a Win 10 install disk.
    (caveat- outline instructions only).

    sounds like a Plan.Will make a fresh install on an external HHD and follow your advice indeed
    fingers crossed now

    maybe one more thing

    this is the state of my SSD where is located my corrupted OS.Would you create an image capture only the C drive or including the FAT partition (named MY here) and the System recovery partition (Volume N)?

    For the purposes I've mentioned, and a clean install to a different drive, you only need the Windows partition.

    Why? Because the clean install creates all the others.

    I want to clean this corrupted SSD as much as possible. Is it sensible to wipe these 2 partitions the MY and System recovery one as you mentioned they are being recreated during the new WINDOWS install.

    I'd tend to regard your current disk as one to wipe and reuse. But leave that until after you've attempted the reinstall of your Win 10 OS on another disk. (You will need a spare disk/flash drive of at least around 60% of the used space of your Windows partition for the image file).

    Restoring your image file to the new disk will mean booting from a boot disk and running MR from that.

    hello

    I cant get it working.

    I have installed Windows on a SATA HDD empty space, no problem to make the PC boot in this new OS

    I have created a system image with Macrium reflect and verified it in the software, also no problem

    now flashing my corrupted OS image onto the new OS didnt do anything, at reboot, Windows go straight to this new vanilla OS I have installed without me being asked to repair it as you were suggesting it would


    I tried to flash the image from within my new Windows OS and also from a Macrium reflect boot rescue drive but I am getting the same outcome in both cases

    can you guess what am doing wrong?

    Hi, you restore an image - 'flashing' refers to flash memory.

    I suggest in all of this when installing your OS you should only have 1 disk in your PC to avoid complications. (Sure, it shouldn't be necessary in a clean environment).

    1. Check the disk image you created.
    Explore the image file with MR. Does it contain Windows with you personal files and folders and installed programs?

    2. Your target disk:
    If you clean installed Windows to this, why is there a large partition before the Windows partition? (F: 880Gb)

    3. Just to check: (skip to Try this if this is what you've done and seen)
    You should be restoring the image from your external drive (assuming your image is on an external drive).

    To do that, you either use Kyhi's disk, boot your PC from that, plug in your external disk, run MR.

    Restore, browse to the image file of your Windows partition.

    Rescue a system with the Windows PE environment

    You should see a dialogue showing data being transferred which should take a little while.

    When that's complete, close MR.

    Try this: Boot from Kyhi's disk, start file explorer. Browse to the Windows parition on your internal disk.

    Do you see files and folders belonging to Windows, including your installed programs and personal files?

    Take a photo or create a screenshot if you can.

    thanks again for trying to help.let me clarify below

    1. Check the disk image you created.
    Explore the image file with MR. Does it contain Windows with you personal files and folders and installed programs?

    The MR image is almost 60Gb in size but an "explore image" run in MR shows only the folder structure as very minimal, I dont get that.

    2. Your target disk:
    If you clean installed Windows to this, why is there a large partition before the Windows partition? (F: 880Gb)

    the target disk is a SATA internal HDD that had 2 partitions on it, one for Games and one for my Media.the volume F is the one storing media files

    the Volume G is where additional Windows Programs and some games were installed, I am OK to lose this if I have to wipe this partition after I cleaned up this mess on my machine
    .

    3. Just to check: (skip to Try this if this is what you've done and seen)
    You should be restoring the image from your external drive (assuming your image is on an external drive).
    The image of my corrupted OS is indeed on an external drive. I did use MR recovery disk to try to restore this image onto the newly created windows OS, not Kyhi disk

    To do that, you either use Kyhi's disk, boot your PC from that, plug in your external disk, run MR.

    Restore, browse to the image file of your Windows partition.

    Rescue a system with the Windows PE environment

    You should see a dialogue showing data being transferred which should take a little while.

    When that's complete, close MR.

    Try this: Boot from Kyhi's disk, start file explorer. Browse to the Windows parition on your internal disk.

    Do you see files and folders belonging to Windows, including your installed programs and personal files?

    will try this before the restore Option

    Take a photo or create a screenshot if you can.

    1. Check the disk image you created.- do you see there all the folders you see if you explore the original partition or is anything obviously missing? Your comment suggests you think so.

    - if all present, great- should be a valid and usable image.
    (That's just a check to see everything's ok in terms of having imaged the correct partition and got what you intended)
    Note too that being able to image it correctly means the clusters are ok.
    What we don't know is if, for example, the registry is corrupt or not.

    2. Your target disk:
    If you clean installed Windows to this, why is there a large partition before the Windows partition? (F: 880Gb)

    - so long as that's a partition you intended to keep- that's fine.

    You will have to use Diskpart command to find out the System Reserved partition drive letter.
    The output of the below commands may display the name of the System Reserved partition as only System or ESP.

    Type diskpart and press Enter.
    Type list volume and press Enter.
    Under the label row, find the label System Reserved and note its corresponding Volume number.
    Now type select Volume=N and press Enter, where N is the Volume number you noted earlier.
    Now type assign letter=w and press Enter.
    Type exit and press Enter.
    Type bcdboot C:\Windows /s w: /f ALL and press Enter.


    Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.
