Operation steps:

1. When encountering an error, such as no boot.wim, you can solve the problem by the following method.

2. First, you need to make sure that there is a hidden folder of $Windows.~BT, which can be found in the root directory of the C drive. To find the hidden file $Windows.~BT on the C drive and confirm that it is larger than 3G, it is understood that the current file size is between 3G and 6.9G. If you are not sure if it is downloaded.

3, please open C:/Window/SoftwareDistribution/Download/c9c1f550a73c72c48a98294db176f702ddb956a8 there is a big $Windows.~BT file is still there, it is still downloading, and when it disappears, you can proceed to the next step.

4. Copy the files in the hidden file of the C drive to any disk except the system disk.

5, find Setupup in the Sources folder on the CD to open in administrator mode, then you can install the system. (If you find that the file suddenly becomes smaller after opening, please go to the recycle bin to restore it).

6. If there is any operation, $Windows.~BT only has 10M left, delete the files in C:\\Window/SoftwareDistribution/Download/and the $Windows.~BT folder, and then refresh it. Windows.~BT will reappear, and then wait for the download to complete.
