  • Generally speaking this issue happens when the system partition (Hidden) is too small.  You need to use a 3rd party tool like easeUS partition magic to increase its size from ~100Mb to around 400Mb

  • Hi,

    According to your description, there are two possible reason for current error message.

    Reason 1: There is something wrong with the file system of system reserved partition.

    Reasons 2: No enough space in system reserved partition for the upgrade.

    In most case, this message occurred because your system hidden partition is too small. In order to resolve this issue, many users choose use the third party software, but if you don’t want to use it, I suggest to follow the steps that are mentioned in this link.
