    New Windows 10 Installation on new SSD made old Windows 10 on Old SSD Unbootable


    I installed a new Windows 10 OS on a new SSD without any issues. After I finished checking the new Windows 10 installation I noticed that the boot screen now shows 2 Windows 10 to boot into. The one that goes to the new Windows 10 OS started with no problem, but the one that goes to the old Windows 10 OS clearly doesn't work. My old Windows 10 OS is on a separate SSD.I have my USB Windows 10 boot drive and I've used Startup Repair on the old windows 10 volume, but couldn't repair it. I'm not sure what to do now. What information do I need to provide to get my old Windows 10 installation back u

    :)

  2. New windows 10 installtion on New SSD - wont boot unless old SSD present

    It seems you installed Windows while the both SSDs were connected. This would have caused your current problem. Maybe it is sufficient to do this:

    1. Launch the Disk Manager.
    2. Right-click drive C:, then mark it as "active".
    3. Shut down Windows
    4. Open the BIOS and tell it that the new SSD is the primary boot device.
    5. Disconnect the old SSD.
    6. Boot up normally.

    If this does not work then you might have to do this:

    1. Disconnect the old SSD.
    2. Re-install Windows on the new SSD, using the Media Creation Tool.

  3. Old SSD to new computer

    I have an old SSD that I would like to install and use on a new computer that already has one SSD and on HD. Windows is installed on the new computer on the SSD. However, windows was also installed on the old SSD I would like to move to the new computer.
    When I hook up the old SSD windows will not start and goes to blue screen with options to recover, use different version of windows, etc. As soon as I disconnect it, windows boots right up again. How do I format the old one to get windows off of it to use
    it as storage?

    Windows 10 Installation to new SSD while keeping old HDD

    Installed a new SSD, so my PC now has two drives. Have been running Windows 10 on the old HDD. I want to install Windows 10 on the new SSD. Using the Windows ISO DVD I made there is no choice where to install WIndows 10. I am not sure how to remove Windows
    10 from the old HDD and install it on the SSD to speed up boot.

    I read where you cannot remove Windows 10 from the original HDD. Not sure if that is true.
