SSD Clone - on Restart system states "No operating system found"

Darryl 26 Reputation points

New HDD clone to SSD.

Windows 10 starts on power on with no issues.

Windows 10 on a restart will state "no operating system found".

I've done the clone process with different software - Samsung and Reflect. Same outcome.

The original HDD still boots and restarts without issue. Its just older and slow.

    Hi @Darryl

    If you see the “ Operating System not found ” boot error message on your computer, it means that no operating system bootloader has been found on the current disk. I suggest you boot the SSD with the OS again as cloning might not always be done properly.

    Below are some of the reasons for this error message.

    1. The computer input/output system (BIOS) does not detect the hard disk drive.
    2. The hard disk is damaged or corrupted.
    3. The Master Boot Record (MBR) on the hard drive is broken. Note that some third-party programs or disk operations can damage an MBR.
    4. An incompatible partition is marked as Active.
    5. A partition that contains the MBR is no longer active.

    You can try other options from this article

    Hope this resolves your query!!

    Boot up the PC that is having an Operating system not found error and then insert the DVD/USB.
    Then press any key to boot from the external drive.
    When Windows Setup shows up, set keyboard, language, and other required settings, and press Next.
    Then select Repair your PC.
    On the Choose an option screen, click Troubleshoot.
    Select Advanced options and open Command Prompt.

    In the Command Prompt window, type the following commands pressing Enter after each of them:
    bootrec.exe /fixmbr
    bootrec.exe /fixboot
    bootrec.exe /rebuildbcd

    I have a similar issue. I can boot from a shut down no problem, but if I restart from the new cloned SSD, the computer gets stuck booting (ASUS logo) and I'm forced to shut it down using the power button to boot it again. I never get a "OS not found" prompt, so I cannot attempt the suggested solutions. Any dea on how to solve this? I can restart from the old drive without problems

    I've found where I do not have a clean clone you can only install from scratch. Unfortunate but some drives (due to age, corruption, other boot/bios issues) just won't clone.

    good luck.
