    "I am attempting to upgrade my operating system from Windows 10 to Windows 11. Although it initially indicates compatibility, the upgrade process fails, resulting in the error message 'Undoing changes made to your computer' and consistently encountering the error code 0xC1900101."

    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

    I got error code OxC1900101-Ox30018. Blog give instructions for W07. Does the same instructions work for W08?

    Trying to update Windows 8.1 to Windows 10 and got this error message:

    OxC1900101-Ox30018 The installation failed in the First_Boot phase

    with an error during Sysprep-Specialize operation (end).

    I found instructions what to do if receiving this error but it outlines

    the steps having Windows 7. I have Windows 8.1 already installed.

    Question: Does the same steps apply to Windows 8.1 when upgrading to Windows 10?

    How can you solve the error oxc1900101

    Solved

    Solved! or fixed! or whatever! I was able to absorb the extra space in a 3-step process:
    1. resize the System Reserved partition to use the space after it
    2. reboot
    3. stretch the M: data partition to absorb the space after it using the EXTEND -- not RESIZE -- command
    System rebooted and working normally. THX all.
