    WIN 10 automatic boot repair loop

    Hi i have another notebook and also another problem
    Lenovo brand - it had win 8, upgraded to win 10, clean install with correct key and activation
    After some time it got stuck on Automatic repair on boot - i mean boot loop
    - it do not work,
    After turning off automated repair i got error
    File: \Windows\system32\config\system
    Error code: 0xc000014c
    - on some forums i found that it could be error in registry file
    Could be caused by bad hardware or only windows is bad?
    I am trying to do factory reset, it takes very long time - it was stuck on 13 % for 30 minutes, now it is on 15%

    The notebook was repaired few weeks ago - it had one ram stick bad. - that was unplugged.

    Thank you, sorry my language

    upgraded to win 10, clean install with correct key and activation
    After some time it got stuck
    Hi, just to clarify- do you mean

    a. you upgraded from Win 8 to Win 10 - and this worked for (some period.... days? weeks?)
    b. You then decided to do a clean install of Win 10.
    c. During this installation process, it went into an automatic repair loop.


    Assuming that's correct:
    First, please check your disk. As you can't boot please dowload and create Kyhi's boot disk from the top of the Software and Apps section and boot your PC from that.

    Run HD Tune and post a screenshot of the result (Health Tab).
    To post a screenshot please use the Insert Image icon above your post to the left of the video icon. Thanks.

    Run Minitool Partition Wizard, expand columns as necessary to make sure text is visible and post a screenshot of that.Here are instructions on how to do a clean install:

    Note you have to download a Win 10 iso and create a bootable disk from that, then boot your PC from that, and delete all Windows related partitions. Did you do that?

    Is the build of Windows to which you upgraded different from the one you've used for the clean install?

    Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.

    Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

    Please type below commands into Command Prompt and for each command you have typed press Enter key.

    Ren  C:\windows\system32\config\SAM         SAM.BAK
    Ren  C:\windows\system32\config\SYSTEM      SYSTEM.BAK
    Ren  C:\windows\system32\config\SECURITY    SECURITY.BAK
    Ren  C:\windows\system32\config\DEFAULT     DEFAULT.BAK
    Ren  C:\windows\system32\config\SOFTWARE    SOFTWARE.BAK
    Copy  C:\Windows\System32\config\RegBack\SAM         C:\windows\system32\config
    Copy  C:\Windows\System32\config\RegBack\SYSTEM      C:\windows\system32\config
    Copy  C:\Windows\System32\config\RegBack\SECURITY    C:\windows\system32\config
    Copy  C:\Windows\System32\config\RegBack\DEFAULT     C:\windows\system32\config
    Copy  C:\Windows\System32\config\RegBack\SOFTWARE    C:\windows\system32\config

    This procedure assumes that Windows Vista/7/8/8.1/10 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.

    Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.

    Yes, good idea, but basics first... maybe there's a reason the problem occurred. We don't want to build a house on sand. Bear in mind the PC was repaired... so it has history.

    A. the win 8 was upgraded to win 10 few months ago
    B. after upgrade to win 10, user extracted key and installed clean win 10 - about 2 weeks ago
    C. the system worked fine until - some critical update

    the system is same and also ISO is same. - made by original microsoft utility.
    I have installed many notebooks with that bootable flash drive

    Good.. now's the time to start using disk imaging routinely... if you have a disk image, even if your disk fails, you can restore it to a new disk far more quickly than a clean install and reinstalling everything etc.

    If you don't yet do that:

    Here's my write-up on the value of disk imaging.

    Everyone who contributes regularly here uses and recommends disk imaging.

    If you use it, you can recover from:
    - a failed disk drive (restore to a new one)
    - ransomware (which encrypts your disk)
    - user error
    - unrecoverable problems from failed updates to problem programs
    - unbootable PC (hardware faults aside)

    Images also act as a full backup- you can extract files too.

    You can even use images to help you move more easily and quickly to a new PC.
    Can be used with Laplink software to transfer your build automatically to another PC

    Imaging can even help you sleep at night knowing you have a second chance.

    Creating disk images lets you restore Windows and all your imaged disks and partitions to a previous working state from compressed copies you have created and kept updated on external storage media, quickly and probably without technical help.

    Many here recommend Macrium Reflect (free) as a good robust solution and more reliable than some others. It’s
    - more feature rich
    - more flexible
    - more reliable
    than Windows Backup and Restore system images.

    It's well supported with videos, help and a responsive forum.

    There are other such programs, free/commercial, some with simpler interfaces, but Macrium R is one of the most robust and reliable.

    How long does it take?
    SSD+ USB3 - maybe 15 mins for the first system image, less thereafter
    HDD + USB2 - maybe 40-50 mins
    That’s with little personal data, few programs installed.
    - of course, depends how much you have on C:
    (You can and should image all your partitions and disks)

    Once you've created your first image, keep it updated with e.g. differential imaging- which images just changes from the first image, more quickly, and creates a smaller image file.

    You need a backup medium - say- twice as large as the total amount of data you are imaging to keep a reasonable number of differential images. This will vary dependent on the number of images you keep, so is only a rough practical guide.

    Some comment that system restore isn't always reliable; if it works and solves the problem, great. But sometimes restores won't work or fail. And of course a restore point only covers a limited number of aspects of the system. That’s where disk imaging comes in.

    (There's a tutorial on Macrium in the Tutorials section, and a couple of videos in the user videos section on this forum)
