Operating system not recognized, can not update windows

I can't update microsoft products, or get online as my operating system has become "unrecognizable."  This prevents me to access patches from microsoft online, or get updates.  I tried to repair the installation, but that doe not work either.  All other features are the same, no noticeable problem.  Windows XP Professional


You can try running "sfc/scannow" from the command prompt. How do to run the command prompt - click on "Start" - "run" - write CMD , and then click OK.

  • Operating system not found - Windows 7, Sony VAIO

    When I start my laptop, it gives the error operating system not found. I have a repair disc, a recovery disk and also a backup system image. I am able to do nothing, as the laptop does not go past this message. In the past, I used to get this error once or twice daily, but when I re-set with Ctrl + Alt + Delete, the system would begin. No critical errors were found in the Eventlogger. How to start the repair process?

    Hi vasanjs,

    1. did you of recent changes on the computer?

    This problem may occur if one or more of the following conditions are met:

    (a) basic input/output system (BIOS) does not detect the hard drive.

    (b) the hard disk is damaged.

    (c) sector 0 of the physical disk has an incorrect or malformed master boot (MBR) record.

    Note  Some third-party programs or alteration of the disk can damage an MBR.

    (d) an incompatible partition is marked as Active.

    (e) a partition which contains the MBR is no longer active.

    Method 1

    I suggest you update brings input/output system (BIOS) to the latest version by contacting the manufacturer of your motherboard or computer and check if it works.

    Important: Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

    Method 2

    If the previous step fails, then I suggest that you perform repair system on the computer and check if it works.

    Hello shessy49, welcome.

    I would recommend that we run a SFC (System File Checker) first scan to see what he finds. Try this:

    1. click on START
    2 type "msconfig" (without the quotes) and press enter
    3. go to the "Startup" tab and uncheck all the entries displayed
    4. click on 'Apply' at the bottom right
    5 restart your computer

    After the reboot

    1. click on START
    2. Type "cmd" (without the quotes). Right-click on the result at the top of the menu START and select 'run as administrator '.
    3. type "sfc/scannow" (without the quotes) and press enter

    If the question started very recently, you can try a system restore:

    1. click on START
    2. click on "all programs".
    3. click on "Accessories".
    4. click on "system tools."
    5. click on "system restore."

    6 follow the prompts shown to restore your system to a date before the problem started. Although the system restore does not target the personal data, it is recommended that you back up all data such as music, photos and documents in case something is not bad.

    Hello... My laptop out there today and I'm trying to start it, it says "operating system not found '... I guess I reinstall windows Vista but I can't find any cd/dvd... I dontt think that I was given when I bought my laptop a few years ago... Do you think I can get another copy (free of charge)) L


    If you have never received a recovery disk when you bought your laptop there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Ask them to the proper key sequence.

    Also some manufacturers have more available recovery Vista disc.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

    Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

  • Windows Vista has crashed, "the operating system not found" error, can I load Windows XP on a partition?

    I have an Acer Aspire 5516, with pre-installed Windows Vista. I didn't know that it did not come with a recovery disk UNTIL my system crashed! During a routine virus scan, I got a blue screen saying a major problem has been found and the system has been shut down. I followed the instructions to gracefully shut down my laptop. When I turned this back on after the "Acer" logo he went to a black screen with info on my computer and the last line States "not found operating system". That's when I discovered there was no recovery disc & it is integrated into the system. To access this system you we F8 to enter safe mode, then Alt F10 to access 'erecovery management system. Neither one of these functions operate! Still getting the black screen with "operating system" not found I have a Windows XP my laptop previous. What I was wondering is if I can load on my Acer, possibly on a partition, in order to be able to get into my laptop and save all of my files? I'm terrified of losing everything I have! I have thousands of pictures that I can't replace. If anyone can help please do! I am on a very limited income & can not really afford professional help. Thank you very much in advance!


    normally with an Acer you press Alt + F10 at startup to start the hidden recovery partition recovery, not F8, then this combo

    but you do not have an option to save your data, that

    in daily use acers normally have a system partition, a partition of data to save your data, etc. to and also this hidden partition recovery

    and read this on data recovery, too;

    Data recovery

    1. remove the hard drive and it slave in another computer

    2 buy or borrow a USB disk drive hard put in yout case then plug it into another computer and read the hard drive like this

    3. try Knoppix


    BUT this method 3 depends on your hardware in the computer that failed

    read this information about method 3:


    Download/save the file Knoppix Live CD ISO above.


    Download the Vista software from the link above.

    After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

    Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

    Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1 in the boot order.

    Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

    When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

    Click on the icons of hard drive to open and to understand which drive is which.

    Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

    Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

    I was reset my pc because of the way of a lot of information and a power cut interrupted and now I just get the operating system not found.

    I see three things at this point in time:

    I tried to boot from the start menu by pressing F9 while restarting, but no solution met! I also tried to boot from EFI file, but does not because no options that are there found.

    The disc is also OK, checked the BIOS settings option.

    Now what to do?

    Spoiler (Highlight to read)



    Let me welcome you on the HP forums!

    I read your post about the operating system not found since the Win10 Upgrade failed and tried to help.

    One of the things that happened during the upgrade:

    (1) it mostly completed but failed in the writing of the new boot loader files

    (2) it failed early in the upgrade, screw up your PC as well

    Allows to process 1) first - by recreating the bootloader files.

    You need access to a PC for this phase of work in order to create the necessary support to fix your PC boot loader.

    Once you have that, please download and create the Win10 installation media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10

    Note that when you download and build install media, the default tool corresponding to what is already installed on your PC (as in home for the House, and 64-bit to 64 - bit).  While you CAN change these settings, are NOT. If you do, the media that results will be different and will force you to enter a NEW product code.

    Boot from the media that you have created and follow the instructions in this link: http://www.tenforums.com/tutorials/2294-advanced-startup-options-boot-windows-10-a.html

    You will need to go to the Advanced Options screen and click on startup repair.  You will probably need to run Startup Repair three times for him to fix all the boot loader.

    Once completed, your PC should start OK.

    If this does not work, then we are on option 2) - which is not good news.

    While Microsoft says there is no risk in the upgrade of Win10, because they allow you to believe that you can always return to your BONES and the original installation program within 30 days, the ugly fact of the matter is that the Win10 GoBack feature turned out to be unreliable - and when she fails, she can let machines in a State corrupted - that does not always happen , but it happens often enough to be a problem and you will get no warning beforehand that he goes to the trash your PC!

    If this is not enough, the Win10 upgrade is known, in some cases, corrupt partition recovery stored by the OEM that built the original machine.  It's pretty much guarantee that no HP recovery will work.

    What will work restores your computer to its original factory state using HP recovery media.

    It is a set of DVD and a CD or a USB key, which will erase the hard drive (removing all data, applications and settings, reinstall the original OS, drivers and utilities for HP. In some cases, you will be able to order a USB instead of discs.  You must order at HP; they cannot be downloaded.

    You can look online for recovery from the paged media related: http://support.hp.com/us-en/drivers

    Once there, enter your product name or number. On your software page and download the drivers, select your operating system and version. Click on "Update".  If the HP recovery support is available for your computer, down near the bottom of the page, you will see an entry for the command Recovery Media-CD/DVD/USB. Click on the symbol '+' to expand this entty and click on order to press for more details.

    Or, if you prefer, you can do the same by contacting HP Customer Service:

    If you live in the United States or the Canada, details are on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

    If you live elsewhere, contact details are on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

    NOTE: once you get through, stay on the line until you are finally able to talk to someone ' one - it can take a while!
    However, HP customer care is generally not available on weekends, so you will have to wait until Monday to contact them.

    Don't forget to read through the material in the linked thread before attempting the recovery: http://support.hp.com/us-en/document/c00707939
