    Sysprep error during win 10 upgrade

    Hi there. Using the media creation tool (both usb and ISO) I get an error. Something like "installation has encountered an error during first_boot with sysprep." In not at my toshiba laptop at the moment so the wording may be a little off. Upgrading from my 8.1 current os. Google is not being any help so I decided to make a post. I just read about removing my eset antivirus before upgrading so I will remove that and my malwarebytes program as well and try again. But if anyone else has had this error I would appreciate any advice.

    Hi, my first post is for give you some support xD. I've tried to fix since yesterday with this error code:

    Error "0xC1900101 - 0x30018 - Error en la instalación en la fase FIRST_BOOT con un error durante la operación SYSPREP

    Yesterday I try to fix it with disabling this:

    - secure boot disable
    - no malware soft
    - antivirus off (ms defender)
    - not usbs
    - ssd on, hdd off
    - not framework 3.5

    And a lot of things I don't remmeber haha. Finaly I reinstall w8.1 and ONLY I downloaded Windows updates (no card drivers, no motherboard drivers, etc). After of this, I download media tool from Windows website and installing the upgrade (no reservation or Windows update process).

    I've tried to install w10 over 10 times and it always stucks on 32% (general count) and 6% (installing features). One thing I can tell you, I think that this error code is about video drivers....because when count pass from 32% to 35% the image improve like if the drivers would have been installed. It's about drivers, and the best way to be sure it's a new w8 OS, it's a ****, but it Works xD

    My advice is try to reinstall win8 and upgrade it to w10 (to get the activation), after of this, make a clean w10 instalation by USB.
