    “Operating system not found” Error on Windows 10

    I just started to get this message on one of my computers but now I cannot replicate it. I copied all of my data off the computer last night so that I could try to get to the repair option at bootup. I shutdown my computer today after all of the files were copied and inserted my flash drive right after startup so it could boot from the usb drive but I never got the setup screen to do the repair. I have repeated tried to get to that screen but the computer will just boot normally now. I want to make sure I do not have that problem again so is there a way to run the repair without booting at startup?

    Note: I still have an open thread for another computer of mine that was having a very similar problem that I have not resolved.

    Microsoft Announces Windows 10 Operating System

    Microsoft Corp. on Tuesday unveiled its next Windows operating system, Windows 10, and gave a first look at an early technical preview for the PC available Oct. 1. The announcement highlighted advancements designed for business, including an updated user experience and enhanced security and management capabilities. The company also introduced the Windows Insider Program, kicking off its largest-ever open collaborative development effort to change the way Windows is built and delivered to best meet the needs of customers. Program participants will receive the technical preview of Windows 10 and a steady stream of builds through the development cycle to use and give feedback on.

    "Windows 10 represents the first step of a whole new generation of Windows, unlocking new experiences to give customers new ways to work, play and connect," said Terry Myerson, executive vice president of the Operating Systems group at Microsoft. "This will be our most comprehensive operating system and the best release Microsoft has ever done for our business customers, and we look forward to working together with our broader Windows community to bring Windows 10 to life in the months ahead."

    Windows 10: familiarity and consistency across devices
    Windows 10 adapts to the devices customers are using - from Xbox to PCs and phones to tablets and tiny gadgets - and what they're doing with a consistent, familiar and compatible experience, enabling even greater productivity. Windows 10 will run across the broadest range of devices ever from the Internet of Things to enterprise datacenters worldwide. Microsoft is also delivering a converged application platform for developers on all devices with a unified app store. Developers will be able to write an application once and deploy it easily across multiple device types, making discovery, purchase and updating easier than ever for customers.

    Windows 10: designed for the challenges of modern business
    Windows 10 builds nearly everything that businesses need right into the core of the product - including enterprise-grade security, identity and information protection features - in ways that can reduce complexities and provide better experiences than other solutions. One area of advancement is in the work Microsoft has done with user identities to improve resistance to breach, theft or phishing. Windows 10 will also help advance data loss prevention by using containers and data separation at the application and file level, enabling protection that follows the data as it goes from a tablet or PC to a USB drive, email or the cloud.

    Management and deployment have been simplified to help lower costs, including in-place upgrades from Windows 7 or Windows 8 that are focused on making device wipe-and-reload scenarios obsolete. Businesses will also have the flexibility to choose how quickly they adopt the latest innovations and influence continued improvements. In addition, organizations will be able to customize an app store specific to their needs and environment. The intent is an app store that will allow for volume app licensing, flexible distribution, and the ability for organizations to reclaim or reuse licenses when necessary.

    Technical preview PC productivity
    The early technical preview of Windows 10 demonstrates new levels of flexibility, navigation and familiarity through the Windows experience. Features include these:
    • Expanded Start menu. The familiar Start menu is back, providing quick one-click access to the functions and files that people use most, and it includes a new space to personalize with favorite apps, programs, people and websites.
    • Apps that run in a window. Apps from the Windows Store now open in the same format that desktop programs do. They can be resized and moved around, and have title bars at the top allowing users to maximize, minimize and close with a click.
    • Snap enhancements. Working in multiple apps at once is easier and more intuitive with snap improvements. A new quadrant layout allows up to four apps to be snapped on the same screen. Windows will also show other apps and programs running for additional snapping, and it will even make smart suggestions on filling available screen space with other open apps.
    • New Task view button. The new Task view button on the task bar enables one view for all open apps and files, allowing for quick switching and one-touch access to any desktop created.
    • Multiple desktops. Instead of too many apps and files overlapping on a single desktop, it's easy to create and switch between distinct desktops for different purposes and projects - whether for work or personal use.
    Open and collaborative development
    The introduction of the Windows Insider Program demonstrates Microsoft's continued commitment to working closely with customers to help shape the future of Windows. Windows Insiders will be able to give feedback on early builds of the product throughout the development cycle. The program will include various ways for Windows Insiders to engage in a two-way dialogue with Microsoft, including a Windows Feedback app for sharing suggestions and issues and a Windows Technical Preview Forum for interacting with Microsoft engineers and fellow Insiders. More information on the Windows Insider Program and the technical preview can be found here.

    Windows 10 Tweaks

    Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

    Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

    • Open a new Explorer window.
    • Click View in the ribbon.
    • Click Options.
    • Under General, next to “Open File Explorer to:” choose “This PC.”
    • Click OK

    Error: "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system"

    Hi Stephen,

    I realize the inconvenience you are facing in accessing the operating system. Now that you have me with you let me take care of this.

    Do let us know if you are able to see Windows 7/ Windows 10 operating system while rebooting the device?

    As you are unable to boot the operating system, this issue might have occurred when the boot files are missing or corrupted.

    I suggest you re-built the boot rec by following the below commands and check if it helps.
    You will have to use Windows 10/7 installation media to follow the steps to boot into Recovery Environment and try to rebuild BCD.

    Step 1: I suggest you to create an installation media for
    operating system using the media creation tool

    If system boots to Windows 10:
    Installing Windows 10 using the media creation tool

    If system boots to Windows 7: Download Windows 7 Disc Images (ISO Files)

    Step 2: After preparing the installation media, insert it hard reboot the device and follow the below:

    • Boot into Windows Recovery Environment using the Windows 10/7 installation media.
    • Click on Repair your computer.
    • Click on Troubleshoot and in the Advanced options.
    • Select Command Prompt. Type the following commands into the prompt and press Enter key after each command.
    • bootrec /fixmbr

    • bootrec /fixboot

    • bootrec /scanos

    • bootrec /rebuildbcd
    5. Restart the computer.

    NOTE: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting
    from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

    Hope it helps. Reply to the post with an updated status of booting the operating system for further assistance.

    Thank you.
