    How to fix Windows 10 stuck at 25% installation or error 0xC1900101 - 0x20004

    From the article below - but my recommendation would be to use the "Upgrade this PC now" option from Windows Media Creation Tool (google Windows 10 media creation tool if you don't know about it already):

    Steps to fix Windows 10 stuck at 25% installation or error 0xC1900101 - 0x20004

    Step 1: Ensure that you install Windows 10 via thumb drive or from a CD/DVD, as the Windows 10 update method is still buggy and unstable.

    Step 2: Disconnect all peripherals or external devices connected to the PC, apart from the installation media or optical drive, keyboard, mouse and monitor.

    Step 3: Also disconnect the SATA cable of your second DVD drive and extra storage drives, except the one on which you want to install Windows 10.

    Tried this method and fails even with using dvd. Maybe I will have to wait a few weeks to see if Microsoft corrects the upgrade process
