Windows 10: I need a Windows 10 1709 repair disk!

    Will it be possible for me to do a clean install of Windows even though the current boot files are causing problems? Will they be overwritten with a new install?

    If this can't be fixed it looks like a new laptop which I want to avoid!

    Any help greatly apppreciated.

    Rufus - Create bootable USB drives the easy way rufus will create a bootable usb drive as required minimum 8gig.
    download the latest win10 iso file (media creation tool) download to the hdd
    follow the directions on rufus interface to complete creating the bootable usb stick. make sure you direct rufus to the place on your hdd where the iso file is stored so it can copy the iso to the usb stick.(click the iso icon in rufus)
    clear your c drive partition even the partition as well (clean completely)
    boot the usb stick and install win10 its quick to do so and saves you a lot of time trying to repair the system

    Hi johnebadback,
    I already have the Windows 10 1709 iso burnt on a DVD which works OK, I'm using it now. The problem is I don't know how to repair/correct the damaged bcd\boot file so that I can boot from the windows that is already on the system. It isn't a question of 'have I got Windows or not', as I do have it.

    If I cannot repair the boot files I'm trying to find out if I can install a clean windows 10 on to my C:\ drive, in other words, will the install find the C:\ drive and allow a clean install and does it create new boot files? I'm assuming I will need to format the C:\ drive once I can get to it.

    And my other concern is, if I format the drive will Windows 'know' that my copy has already been validated or do I lose that?

    Thanks for the suggestion!

    I know nothing about Ubuntu and for me that will cloud my thinking as it is yet another thing to get my head round! But thanks for the suggestion.

    This junior is 83...

    I'm looking for repair options.
    Please post the commands if available for the problem or mistake.

    For these images please make sure that the text is well seen on the images:

    Open command prompt and type:
    list disk
    list volume
    select disk 0
    list partition
    select partition 2
    detail partition
    assign letter=b
    list volume
    bootrec /fixboot
    bootrec /fixmbr
    bootrec /scanos
    bootrec /rebuildbcd
    bcdedit /export c:\bcdbackup
    attrib c:\boot\bcd -h -r -s
    ren c:\boot\bcd bcd.old
    bootrec /rebuildbcd

    It may take a couple of days to find alternative repair options.
    There are ways to format the partition and rebuild the BCD.
    I'm looking to see if a good resource can be found.

    There are backup plans.
    There is registry repair which can fix some boot issues, boot rescue and clean install.

    Hi zbook,

    I really appreciate tyour efforts on my behalf, I know how time-consuming research can be!

    The last two chkdsk tests went through clean but this is the thing that I'm not sure about and I haven't been able to re-create it so that I can say N.

    "I've been going through the list of commands you gave me and I remembered that when I first did the bootrec /rebuildbcd it came up with Total identified Windows installations: 0 and then when it asked me if I wanted to add installation to the boot list I very stupidly typed Y. I obviously wasn't aware of the implications and what it meant".

    I will crack on with your list, I apologise for the poor quality of my mobile phone screenshots, I'm not sure that I can improve them but I will try.

    do you mean the paid version or the free one? Just had a look at the free one options but cannot see anything about boot loader repair?

    OK got it. The free version won't allow me to create a recovery CD which I need for the faulty system!

    Maybe you did not make a mistake.
    If there are 0 installations there is unlikely a way to add to the boot list.
    So don't fret about it.
    One way or another there are options.

    If you want to try the reg backup that can be done with these commands:

    Please take pictures of the commands and results and post images into the thread:

    Let's see if this is a possible fix.

    1) boot to the Windows 10 iso
    2) it may take 5 minutes displaying the windows icon
    3) Use the default settings for language, time, currency, and keyboard
    4) click next
    5) In the left lower corner click Repair your computer
    6) click troubleshooting
    7) click startup repair (it is expected to fail)
    8) click system restore (it is expected to fail)
    9) click command prompt
    You should see a pop up with title bar: Administrator: X:\windows\system32\cmd.exe
    This is the registry backup method:
    For each step you must see sizeable file sizes for this to work.
    If you see zeros the method will fail.
    The command: dir
    will be used each step to make sure you are in the proper location and check the size of the files
    10) type: C:
    11) dir
    12) type: D:
    13) dir
    Choose the C: or the D: drive to proceed. It should be the windows drive and not the USB drive.
    14) type: bcdedit | find "osdevice"
    This should display the location of the partition and in most cases is the location of the affected drive.
    For this post I will use C: however you should pick the drive letter that you found that has the windows files on your computer.
    The proper drive will display: perflogs, program files, program files (x86), users, windows, etc
    15) type or copy and paste: cd \windows\system32\config
    It should display: C:\windows\system32\config>
    16) type: dir
    It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.
    All of the file sizes should be sizeable. If it displays zeros then abort.
    Make a new directory and name it backup or something similar.
    17) type: MD backup
    Copy all of the files into this new directory.
    18) type or copy and paste: copy *.* backup
    It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.
    Change the directory to regback
    19) type: cd regback
    It should now display: c:\windows\system32\config\regback>
    20)type: dir
    It should display: default, sam, security, software, system etc
    All of these files must be sizeable. If it displays zeros then abort.
    21) type or copy and paste: copy *.* ..
    It should now display:
    Overwrite ..\default? (yes/no/all):
    22) type: a
    It should now display: sam, security, software, system and that the files were copied.
    23) type: exit
    24) click turn off your PC
    Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.

    If the repair works then you must consider the repair fragile.
    1) Make a brand new restore point
    2) Backup all files to another drive or to the cloud
    3) Make a backup image using Macrium:
    Macrium Software | Macrium Reflect Free
    4) Place the backup image onto another drive or into the cloud.
    5) Check the Drive with HD Tune:
    Post images of the test results for these tabs:
    a) Health (SMART)
    b) Benchmark
    c) Full error scan

    I'm not sure if I'm missing something here! I already have the Windows 10 iso on CD. I am currently using the Win 10 repair tools.

    I cannot use the free Partition Wizard as it will not allow me to burn a recovery CD, I would have to buy the pro version.

    I had already tried a similar function in, I think, Macrium Reflect but that didn't fix the fault.
