Windows 8.1 Error 0xc0000001

Recently I've been trying to refresh my computer lately because its been running really slow, so i tried refreshing it but at the end it ends up telling me I have a file missing or it needs to be repaired  (file: /windows/system32/winload.efi) and
to insurt a disc but my laptop didn't come with any discs, I don't know what to do. I can't update my apps or even go to my app store. How can i fix this? 

How did you install Windows 8.1? Windows store upgrade? If so, you may need to find Windows 8.1 installation disc to make system refresh. Microsoft doesn't provide any method to make system refresh for the User that upgrade their system to Windows 8.1.
While, if you encounter any problem such as your provide in title, please provide the details about this problem.

  • BCD/boot error 0xc0000001 ~ stuck on broken windows partition

    Okay so I have a macbook pro 2009 and I recently partitioned my hard drive to get windows 7 premium using bootcamp. While installing new software for my windows side it it froze up and I had to do a hardshut down. After I restarted my computer it came up with a black screen that says boot/bcd error - 0xc0000001
    info: an error occurred while attempting to read the boot configuration data.
    It instructs me to
    1. insert your windows installation disk and restart my computer
    2. choose your language settings and then click "next"
    3.click "repair your computer"
    problems I've come across while attempting to fix this
    1. when selecting what operating system to repair after starting up the windows installation disk there are no operating system that shows up.
    2. "repair your computer" option does not work and cannot repair the problem.
    3. cannot hold down option to go back to Mac side because of EFI lock which I don't know the password to it.
    4. cannot get to safeboot for reasons unknown, but holding down f8 doesn't work and holding down FN with F8 also does not work. It just goes to the boot error screen.
    5. System restore does't work either.
    6. went into command prompt and typed sfc / scannow but it says that another scan is in progress but needs to reboot to start. Every time I restart the same message pops up.
    All I really want to do is get back to my mac side so I can delete the partition at this point. But it is IMPOSSIBLE so if anybody knows any solutions please do share. thanks!

    Hi electrovalent,
    I agree with Tripredacus,we seem to miss the important part that we should boot from the UEFI mode for a GPT format disk.To boot from the UEFI mode:
    1.Insert the installation DVD or USB flash drive, and boot the computer.
    2.When the firmware starts to initialize, press the key that opens the UEFI firmware boot device menu, such as Esc, F2, F9, F12.
    3.Select an EFI drive, examples: EFI DVD/CD Drive, EFI USB Drive, or EFI Network Drive. You may be immediately prompted to press a key to boot from the drive to continue.
    Here is a link for reference :
    Walkthrough: Boot Windows PE from a UEFI-based Hard Disk
    https://technet.microsoft.com/en-us/library/hh265131(v=ws.10).aspx
    I have noticed you have tried the "Startup Repair"option before but I would suggest you try this option again .Because we have chosen the UEFI mode this time and this option is usually useful and convenient to repair the boot loader.
    If the issue persists ,try the following command line .I also noticed you have tried the similar command line before but I have made a little modifications according to the screenshots you have posted.
    diskpart
    list vol
    sel vol 2  (Volume 2 is the fat32 volume,this step is not included in the screenshot )
    assign letter=v
    exit
    ren BCD BCD.old (Backup bcd )
    bcdboot c:\Windows /s v:

  • Windows Blue Screen Error Message Appears As Soon As IPod Connected

    Everytime I connect my IPod to my computer, I get the Windows Blue Screen error message. Thought it was the cable, so plugged cable in by itself. No problem. Uninstalled IPod and ITunes software and then plugged in IPod, still got the Blue Screen. The Blue Screen says something about "recent plugged in device problem". It is not the cable, it must be the IPod. Did not have this problem when I bought it. Tried it on labtop and get the same error message. I can't do updater or anything that requires me to plug the IPod into a computer because the Blue Screen appears immediately. When I unplug, the Blue Screen remains and locks up the computer so I have to restart each time. I have tried everything I can think of. Please help.

    Hi Mike thank you for replying,
    I am not able to start the computer in safe mode, safe mode with networking, last good known configuration etc, Each time it quickly blue screens and restarts about two secs into the process.
    I was unable to try a clean OS install from the disk as it gave the blue screen error shown in the original post. The same thing happened when I tried to use the repair option on the XP home disc. So i can't get into the computer at all to start diagnosing the fault, the only clue I have is the error message, and after searching the internet I haven't found much enlightenment from that yet.
    If you can help me out or suggest where to search it would be much appreciated.
    Thx

  • Windows prompting send error report or dont send

  • When I connect my iTouch to my PC (windows 7) an error message is displayed reading "iTunes was unable to load dataclass information from sync services. Reconnect or try again later".

    When I connect my iTouch to my PC (windows 7) an error message is displayed reading "iTunes was unable to load dataclass information from sync services. Reconnect or try again later". I have completely uninstalled and then reinstalled iTunes. I have also completely reset my iTouch to factory defaults. I have even followed all the advice provided previously to other forum member with the same problem. Nothing seems to work. Please help me someone.

    I'm getting the same problem with both my IPad 4 and iPhone 5
    Just started a few weeks back, Since then I have had two Itunes updates.
    Is this something Apple is aware of and trying to fix?

  • Windows-No Disk Error Mess

    I get the following error message upon start-up or reboot for Audigy SE:?Windows-No Disk?c0000003 Parameters 75b6bf9c 4 75b6bf9c 75b6bf9c.... I have the option to Continue-Cancel-Retry??The sound card seems to work otherwise, but this error is annoying and I would like to resolve it. I tried uninstalling and reinstalling the install CD as this is a new install, but the error persists. Can someone suggest a Fix-It?Thanx!?Lawrence

    I have found the Windows No Disk error message to be caused by having a card reader installed in your system in some cases. If you change the dri've letters of the readers from i.e. F: and G: to for example O: and P: (as I did on my machine) the error message will stop. Worth a try.......worked for me. Hope you find this reply useful, unlike the previous wise a$$ replies.

  • Windows - No Disk Error - Please help!

    Windows - No Disk Error - Please help!
    Hi,
    I have the following set up:
    * Lenovo T-61p
    * Windows XP Pro, SP 3
    * HP Photosmart 8250 printer (with nothing plugged into the various card readers, and USB slot in the printer)
    I am getting the following error:
    Windows - No Disk
    Exception Processing Message 0xc0000013 Parameters 0x75CE023C
    0x84C40C84 0x75CE023C
    I have done a lof experimenting and thru process of  elimination, and believe I have determined that this only happens when the HP Photosmart 8250 printer is plugged in to the USB slot of the computer.
    I can stop it from happening by safely removing hardware, and removing the drive that the 8250 creates on your computer when you plug it in.  In my case, this is drive E.  I'm guessing if there was something in the the various card readers, and USB slot in the printer, that's what those would be, but I don't those use those functions of the printer.
    I understand there is more at work than simply the printer, because I did not used to get this error, so some software changed as well, that is scanning all ports, and finding a drive that has no disk, and producing the error.
    A simple google search finds a lot people all over the world having this problem, and are solving it in different ways, because the suspected source is different: Norton, HP, etc.
    I have tried everything I have read, and the only thing that works was my own idea, of manually safely removing the drive the printer creates each time I plug in the printer.
    Anyone every any better, more permanent solutions?  Or know what the real root of the problem is?  What is scanning all the drives and being showing an error message because it found an empty drive?
    Thanks and Happy Holidays/New Year!

    I've been getting the same error on my 4G nano for the past week. I've had my nano for about a month and the first few weeks were fine. Tried it on 2 different computers (Vista and XP) and same problem. Tried it on a 3rd (XP) and it started ok. Problem started coming back after a day.
    I was able to find a quick fix though. I noticed that sometimes the message says something like "iexplore.exe... no disk..." even if I don't even use IE. What I do is end iexplore.exe on task manager before running iTunes and syncing my nano. I don't get the error whenever I do this, but one drawback is that the contents of my nano suddenly pops up in a window - even when disk use is not enabled.
    I've reset/restored my nano dozens and dozens of times to make sure it's clean. Leads me to believe it's a driver issue. Either that or I have a friggin malware problem I can't seem to find.
    I'll be posting updates every now and then. I'm no expert so I'm hoping an Apple expert also steps in to give some input.

  • On Windows Platform, encounters error when trying to open an Indesign document created from MAC

    Hi all,
    On Windows Platform, encounters error when trying to open an Indesign document in INDD format created from Mac. Error received "Either the file does not exist, you do not have permission, or the file may be in use by other application". I am currently using Adobe Indesign CC 9.2 Trial version.
    Kindly advise how can i open this document on windows platform and allows me to edit the document.
    Thanks!
    With Rgds,
    Fiona Choy

    Normally there is no problem to open any INDD opening on Windows, when created on the Mac.
    But Mac user are often not aware on the naming limitations. A file name must not contain /, \, |, :
    It should not contain any extended character, it is not a primary problem but will be, if something links to that file, so avoid also: ÄÖÜäöüß+&
    You can use all other non A-Z a-z, 0-9 and - and  _
    I personally would also recommend to avoid spaces.
    This is valid for the INDD file itself but also for all linked content.

  • Dv6 Notebook "Black Screen" following "Windows Blue Screen" error message. Caps Lock blinking!

    I have a HP DV6 notebook. I left my computer on overnight and the next morning I woke up to find a Windows Blue Screen error message. It said to restart my computer. I was in a rush so I just closed the lid. When I returned I opened the lid and the screen was black. I pressed the power button to restart it and I haven't been able to restart it since. I now have a power light, a black screen and the CAPS LOCK light is blinking twice then a pause! Please help!

    Hi btgclark,
    I understand that you are having an issue with turning on your notebook and the CAPS LOCK light blinks twice and then pauses. The following document 'Computer Does Not Start and the LEDs Blink or the Computer Beeps' will walk you through the steps that you need to follow. For your error code, it means that the BIOS has a corruption failure. This document will walk you through the necessary steps to get this resolved.
    If for some reason this document does not resolve the issue please provide me with the model number to your notebook. I have included a document 'How Do I Find My Model Number or Product Number?'
    Please let me know how this works out for you, thank you.

    I found my solution. As some suggested here,  I looked and found an older iTunes x86 file that needed to be deleted. Once done, my current iTunes works fine and no longer trips the windows 7 126 error alert.
