    Operating System Not Found Error Message


    I cloned my drive and installed a new SSD as the old drive was full. All working really well except windows very slow to bootup >5 mins but working well once running. Thinking the cloning had not worked fully I ran the media creation tool via usb which on reflection was not a good idea. It crashed my PC which will now not bootup and all I get is the OS not found error message. My wired keyboard is completely dead so I cannot tell it to boot from USB. Any help in resolving would be greatly appreciated but please use layman's language.

    :)

    Error Message when updating from Win-7 to Won-10

    Bree
    I followed your suggestions (2nd Aug 19) for installing Win-10. Made the bootable flash drive successfully through the media creation tool. But when I attempted to upgrade and activate to Win-10 (64 bit) from within Win-7 (Pro-32 bit), I got the following error message:

    Error # OxC1900101-Ox20017. " The installation failed in the SAFE_OS phase with an error during BOOT operation"

    I read the diagnostics under this error number and carried out the proposed fixes, i.e. update Win-7, uninstall Malwarebyte antivirus, disconnect all external hardware, e.g. printer, scanner, external hard drives. I then tried to repeat the steps to do the upgrade through the Win-10 bootable flash drive as before. Got the same error message.
    Appreciate any further comments and suggestions as to (a) what does a failure in the SAFE_OS during boot operation mean, (b) what can I do to solve it. Is this anything to do with the hardware in my computer? I listed these in my first posting above.
    Thanks for any help
