    Yes he meant booting into windows and going to command prompt and running the mbr fix command.

    New Details :
    When I install HDD as Internal
    Bios does not detect HDD
    Windows does not detect HDD
    When I install HDD as External
    Most software fail - or are unable to launch unless i turn off the hdd and turn it back on

    Provide a picture of the disk
    Front AND back

    Because some disks get board "bugs" that can be fixed by serial interface

    Tutorial: Fix MBR From Command Prompt in Windows 10, 8, 7

    If MBR is damaged and OS cannot boot, here you can learn how to fix MBR from Command Prompt in Windows 10, 8, 7 step by step.


    By Emily / Last Updated October 16, 2020

    Overview of MBR (Master Boot Record)
    The Master Boot Record (MBR) is a boot sector of any hard disk that identifies how and where the operating system is located. It is created on the very first partition when you install Windows on your computer. It is the first 512 bytes of your hard disk. MBR holds significant information that enables your PC to find and identify the OS location and allows Windows to boot up successfully.


    What happens if MBR is corrupted?
    Now that you might have known the importance of MBR, but what will happen if the MBR is damaged because of a virus infection, drive failure, or an MBR overwrite? Generally, as a result, your computer may fail to boot and prompts one of the following error messages during OS initial:


    Fix MBR from Command Prompt in Windows 10/8/7
    Thus, how to repair MBR so that you can boot the OS successfully? This part will illustrate how to fix MBR through Command Line step by step in Windows 10/8/7. Since Windows 7 and Windows 8/8.1/10 slightly differ in accessing to Command Prompt, we make two respective tutorials for your reference.


    Tutorial 1. Fix MBR via CMD in Windows 7
    To fix damaged MBR using Command Prompt, you have to use the Windows installation CD/DVD to boot your computer since it is unable to boot from the OS. If you don’t have one, you can download Windows ISO files from the official Microsoft website and create a bootable USB drive.

    1. Boot computer from the Windows 7 installation CD/DVD.

    2. At the “Press any key to boot from CD or DVD…”, press any key to boot PC from the inserted DVD.

    3. Select a language, keyboard layout and click “Next”.

    [​IMG]

    4. Select the operating system and click “Next” and tick “Use recovery tools that can help fix problems starting Windows”.

    5. At the “System Recovery Options” screen, click on “Command Prompt”.

    [​IMG]

    6. When Command Prompt launches successfully, type the following command in the given order and hit on “Enter” after each one.

    • bootrec /fixmbr

    • bootrec /fixboot

    • bootrec /rebuildbcd
    Then, you can remove the installation DVD from the disk tray and restart your computer to check if the boot MBR is fixed.

    ▸If the above commands do not work, do as below to restore the boot sector code in Windows 7:

    1. Check out the drive letter of your Windows 7 installation CD/DVD by running commands: “diskpart-> list disk->select disk 0 -> list volume”.

    2. Find out the “CD-ROM” word in the “Type” column.Then check your CD/DVD installation drive letter. If the drive letter is d:\, type the command: “exit d: cd boot dir”.

    [​IMG]

    3. Then type command: “bootsect /nt60 SYS /mbr” and hit on “Enter”.

    4. Remove the CD/DVD from the disk tray, type“Exit” and press “Enter” to restart your PC.

    [​IMG]

    3. When the Command Prompt loads, execute the following commands in order:

    • bootrec /FixMbr

    • bootrec /FixBoot

    • bootrec /ScanOs

    • bootrec /RebuildBcd
    4. Remove the DVD and restart your computer to check if it can boot up successfully.

    ▸If the above commands do not work, do as below to restore the boot sector code in Windows 10/8:

    1. Type “diskpart-> list disk->select disk 0 -> list volume” to check for the EFI partition that was formatted to be FAT32 file system.

    2. Check out the volume number of EFI partition. Supposing it is “2”, you need to type the command: “select volume 2”.

    3. Type “assign letter= g” or other unused drive letters.

    4. When Diskpart successfully assigned the drive letter, you need to type “exit” to close the Diskpart window.

    5. Then run the below commands in the Command Prompt window:

    • cd /d g:\EFI\Microsoft\Boot\: replace “g” with the letter you assigned to the EFI partition.

    • bootrec /fixboot: repair the volume.

    • ren BCD BCD.backup: back up the old BCD and recreate a new one.

    • bcdboot c:\Windows /l en-us /s g: /f ALL: recreate the BCD.
    At last, remove the DVD and reboot your PC.

    If your Windows OS is not installed in C drive, please c:\ with your drive letter in above commands.


    Free alternative to CMD: fix MBR without Windows CD/DVD
    Above is all about how to fix MBR through Command Line using Windows installation CD or DVD. However, if you don’t have one, how can you make it done? Thus, you can switch to the free partition manager-AOMEI Partition Assistant Standard, which helps you to repair damaged MBR without using DVD or CD Instead, you can use this freeware to create a bootable media (USB flash drive) first, boot computer from it and then rebuild MBR in Windows PE environment.

    1. Download, install and run AOMEI Partition Standard on a working Windows computer. And plug an empty USB flash drive (over 8GB) to this PC as well.

    [​IMG]
    Download Freeware

    Win 10/8.1/8/7/XP

    [​IMG] Secure Download

    2. In the main interface, click “Make Bootable Media” and “Next”.

    [​IMG]

    3. Choose your USB flash drive and click “Proceed”.

    [​IMG]

    4. Wait for the process to be done. After that, connect the bootable USB flash drive into the computer which cannot boot due to damaged MBR. Reboot it and enter BIOS to change boot order to boot computer from the USB flash drive.

    [​IMG]

    ▸To give a USB device boot sequence priority over the hard drive, do the following:
    1. Move the hard drive device to the top of the boot sequence list.
    2. Expand the hard drive device to display all hard drives.
    3. Move the USB device to the top of the list of hard drives.

    5. Once login, you will see AOMEI Partition Assistant Standard is running. Right click the system disk and select “Rebuild MBR”.

    [​IMG]

    6. Choose a proper MBR type for your current operating system.

    [​IMG]

    7. Click “Apply” and “Proceed” in the main interface to start rebuilding MBR.

    After you have finished all steps, you can restart your computer to check whether your computer can boot normally.


    Summary
    As you can see, compared with fixing MBR via Command Prompt/DiskPart, AOMEI Partition Assistant Standard is much easier. Moreover, it can fix MBR without using Windows installation CD or DVD, a big bonus for users without enough computer knowledge. Besides, it also has other functions to better manage your disk and partitions such as merging partitions, copying partition to another drive, moving partition, cloning large HDD to smaller HDD/SSD etc.

    I've read those many times, most of these tutorials tend to forget to say that fixing MBR will kill all Data.
    I finally got a diagnosis, now i want to recover data
    im going to try XCOPY in command prompt since recovery tools can't deal with the disk
    SeaTools tests dont even run, so my guess it is dead, still i dont give up.
    since "Command prompt runs in x32" as opposed to Win10 (x64), i might be lucky
    Of course, i might try to fix it, but to me, "a HDD that fails once is only good for leveling a table ..... "

    Once on mac the system froze during a repartitioning process and the HDD became completely unreachable. I used Data Rescue 4 and it was able to save all data (even previously deleted files) to a spare disk and recovered the disk.
    Now that software has version 5 and it seems having a Windows version, too.

    Did you already try pressing the "F8" key repeatedly after powering on the laptop in order to enter the start menu before it tries to boot? Then you can try the "boot from last known configuration that worked" option or whatever it's called now. And if that doesn't work, use the "boot in safe mode option" and that might clear up that transfer process that was stuck in time. Then try rebooting in normal mode. And lastly, some people have had success by unplugging a desktop computer entirely, or removing the battery from a laptop for 20min or so, and then trying again.

    If none of those methods work, you'll have to use another computer to download the Windows 10 media creation tool and create a bootable flash drive to perform a Startup Repair. That should do the following: (Bootrec /fixmbr), (Bootrec /fixboot), (Bootrec /scanos), (Bootrec /rebuildbcd).

    BEFORE anything, do a block level backup on another drive
    It will create a perfect digital copy, even with the errors

    So you can copy the backup over any spare HDD and try several recovery methods on it

    This way, you will NOT loose more data than now :wink:

    Here is one :
    https://hddguru.com/software/HDD-Raw-Copy-Tool/

    If you clone it on a GOOD hdd, you can try many fixes : MBR, partition table recovery ...
    But trying on a BAD hdd will probably create more troubles
