Win7/Win8.1 booking upgrade Win10 failed solution

According to netizen feedback, many Win7/Win8.1 users upgraded Win10 in the early morning by Microsoft's official push, but in the process encountered "Installation failed & rdquo; and other issues, the upgrade can not be carried out. Given this situation, many users choose to enter the Windows 10 pre-download installation folder and intend to install it manually. However, the new problem came again at this time, that is, the installer claimed to be missing the boot.wim file and could not be installed.

However, the user of the organic wisdom downloads the Temp10 installer to the temporary folder <;C:\\$Windows.~BT\\” After copying it to other partitions, start the setupre in the source folder. The exe program can be installed normally.

But there are also users who say that the "Windows.~BT” folder will disappear in some cases, which has a lot to do with its "temporary" attribute. The root cause of this problem is that the system believes that the file in the folder has “completed the mission”; therefore, the content will be deleted, but from the feedback of “Installation Failure”, this is obviously a serious mistake. Therefore, in order to prevent the abnormal problem caused by this folder property problem, you can consider putting the files in the copied folder into the normal folder or changing the folder properties after copying. Remember, don't make any changes to the original “$Windows.~BT” folder to avoid affecting the normal upgrade channel.

▲The original 6GB or more folder is only 140MB inexplicable

Because this push upgrade method is the first time, it will inevitably have some problems in the actual operation process. Microsoft has not yet given an official solution to various problems. If you have any questions or suggestions during the upgrade process, you can leave a message in the comment area to facilitate discussion. After the official solution is released, Xiaobian will inform the users in time, so stay tuned.
