    Inaccessible_boot_device error after upgrade and restart


    Microsoft strikes again...

    Upgrade worked fine using the DVD .iso I downloaded, apart from taking 3 hours.

    Upon restart tonight, I got an endless     Inaccessible_boot_device error loop.

    I was able to revert to Win 7 using the Advanced menu displayed when the boot failed.

    Lenovo Z580 laptop. It still has the original Lenovo restore partition, so perhaps that was part of the issue.

    As soon as I rolled back to Win 7, the system started perfectly.

    Sounds like Win 10 is still not ready for prime time.
