  1. Thank you for your helpful article.

    There is a small error in the “Method 1” section where you write:

    “bootsect /ntfs60 C: (replace drive letter with your boot drive letter)”

    It should be “bootsect /nt60 C:” …

    Thanks again.

  2. Hi and thanks, your number 6 method worked for me but the downside is that i have to keep doing it anytime i restart my laptop which is annoying and when i try to restart my laptop, i get a freaking blue screen of death and i get the automatic repair loop again. Even windows customer care couldn’t help me, they need to fix their sh!t. as always. I am using some microsoft apps like visual studio so i needed windows 10, if i can have my way, i’ll go back to windows 7.
    Anyway what i did was go into the local disk drive/volume “D:” by pressing “D:” and enter, this was where all my program files and all my files where, i don’t know why they where moved from “C:” to “D:”, you can check where yours is by typing “C:” and pressing enter then type “dir” and press enter, if you don’t see your progam files and windows, then just try other letters of the alphabet.
    Next i typed cd “windows\system32\logfiles\srt” and hit the enter key.
    After that i typed “SrtTrail.txt” and hit enter then a notepad poped up, look for any file that is corrupted and copy it, mine was “d:\windows\system32\drivers\nldrv.sys” and it says that it was corrupt.
    After that i typed “D:” and typed the location of the file “cd windows\system32\drivers” and hit enter.
    Then i typed del nldrv.sys and hit enter and restarted my system and it booted up fine.

  3. Thanks for the help. Method 4 was the key for me. To help identify my registry was the issue, I disabled autorepair which gave me a new message when I restarted saying my registry was corrupted. However, step 10 has an omission. It reads:
    copy c:\windows\system32\config\RegBack c:\windows\system32\ where it should have “\config” at the end, or else you are copying to the wrong destination. Your screenshot shows the correct copy location. Thanks again, I spent several hours slogging through this until I found your site, and Method 4 fixed it.

  4. None of these Solutions worked out for me.
    “Impossible determine cause of rebooting “, some kind of rootkit, i just unistalled 2 software without rebooting between them, fatal mistake. One of them was malwarebytes..

  5. I see you are typing from drive “x”. Why is this x? Please explain. I am not using a disk or external source, yet my drive letter is also “x”. I am stuck in “x”. I cannot change to “c” using commands like “CD”. They don’t work. There seems to be some mixup with the letters. Someone with this issue used external software to look at their device and found the c drive had become a ” g” drive, and other drive lettets were jumbled up also. This just happened to me today and I’m lost. This is a good guide bit need checking as typing the wrong thing in cmd prompt can go bad real quick.

    1. your methods to stop the loop locked worked . this allowed a new error to appear. The operating system couldnt be loaded because the system registry file is missing or contains errors. I will try the reg fix method once I get a disk and otp hub. Be aware once you switch the loop off and get the reg error you cannot get back to dos to switch the loop back on again unless you “press the windows key”. I don’t have that key on my tablet so had to buy a USB keyboard and plug it in the otg device. Lol. I’m now going to switch looping back on till I get a disk. Apparently you might need a disk for the original instal, even if you upgraded! Also when you are doing the methods and fixing the loop make sure you have a good charge as you cant see the battery meter. I’ll update once I get my Windows 8 disk..thank you. PS. I might have caused this error by powering off as the tablet was already powering down…was it quietly upgrading? Overheating? I don’t know but that was the last thing I did..

    2. What does this mean please?
      IMPORTANT: Never convert a Basic disk that contains your operating system to a Dynamic disk, as it could make your system unbootable.

      Does this mean a normal instal disk won’t do a repair like the old days with xp?

  6. Being old school I went into bios to see what letters for drives were showing. The tablet bios only showed uefi or “windows boot manager”. Its a basic americanmegatrends bios. I’m stuck.

  7. 2.After completing each command successfully type exit.

    That reads like you exit after each command. I think it might read better to say:2.complete each command, then type exit.

    Or something like that?

  8. Dear adityafarrad!!!
    Your article is very useful to me, I am Vietnamese should speak English is not good, although to use google to translate your post to follow but very easy to understand and repair my machine. When my computer broke down I went to google search many sites only repair ways including microsoft help page, but absolutely no help to me at all. I see so many people do that without doing anything. Can I copy your posts to help them? Thank you very much. Good luck to you always come !!!

  9. number 4 fixed it! cheers mate!

  13. Hello,

    I used Method 7 “Disable Automatic Startup Repair Loop”
    And now my laptop doesn’t start and I can’t open command prompt to disable it
    How can i fix it?

  14. the dskck method worked thanks I needed you command prompt instructions to get to dskck from a rescue disk and the parameters to get dskck to fix it thanks again

  15. Hello All,
    Thank you for trying to help all of us dumb computer folks but I tried all 10 methods and NOTHING worked. I get the dreaded “your pc did not start correctly” and trust me, I went through the entire options of repairing. Couldn’t restart, repair, restore, reset, All Advanced options which brought me back to “your pc did not start correctly.” After a week of this, I will be calling Microsoft for a tech, even if I have to pay for the service. I thought Method 1. the bootrec /rebuild method would work. But, the last entry of bootrec.exe /fixboot – access was denied.

    I do have the Sfcfix application on a USB to run a fix of the system but, and here’s my question to all of you experts: How do I run the application if the computer won’t boot?
    After trying all 10 methods, I’m exhausted!!!!! Please help.

    Thank you

  16. Hello everybody,

    I tried all of the methods and nothing worked to get the windows 10 to start correctly. Please tell me: What can I type at the command prompt to let me use a rescue USB that has the Sfcfix application on it? I have the application but if the system won’t boot, how can you use the application to get the computer up and running? Also, the computer won’t enable safe mode (tried f4 and f5) or any of the re-set 1-9 codes. I get the dreaded: boot critical file C:\windows\boot\resources\custom\bootres.dll is corrupt. and srt\srttrail.txt.
    HELP
    thanks much

  17. I found a way to save your files before doing a full reinstallation of windows. When all methods don’t work.

    Go to Command Prompt.
    Type your os drive C: then Enter
    Then type cd then Enter
    Then type cd then Enter
    Then type notepad then Enter

    Your notepad will open then on the File click Open.
    On the Files of type: change it into All Files to be able to view all kinds of file types.

    *When moving your files put it in a usb.
    *You can’t open the file even if it is an image

  18. Nothing works. Just says preparing automatic repair. Win10 disc, boot disc, remove batt/ac push start button for verious seconds, bios to dvd boot, new ssd for os, nothing changes. What next?
