What to do if the Windows installation source is invalid

The Windows installation source is invalid. This is usually an error we encounter when installing the original system. Novice users may encounter this error and have a headache. They don’t know how to solve it. Here I provide several solutions.

Reasons why the Windows source is invalid:

1. The image is damaged

2. The Pe internal virtual optical drive failed to load

3. Encryption of esd files inside the image

Solution:

1. First, the image is damaged. There is no good solution for this. You can only change the image. Installation, as for the method of detecting whether the image is good or bad, the commonly used method is hash detection, just compare it with md5.

2. The virtual optical drive inside Pe fails to load. In this case, we need to uninstall the virtual optical drive, then reload it, and reinstall it to solve the problem.

3.esd file encryption, this is the key point we want to talk about, and usually, this is the reason why the installation source is invalid:

Due to the high compression rate of the ESD file format, the volume is also small Small, many times the Win10/win8 systems we download online are in this format. As for the installation tools, we generally use WinNTsetup 3.7 or above to install. However, some users find that the "Windows source is invalid" prompt during installation. This is What is the problem? In fact, the main reason is that the ESD file is not decrypted.

Let’s take a look at how to decrypt ESD:

Here the editor recommends using dism for decryption:

Ps :dism After downloading, unzip it directly and put it into a USB flash drive. You can directly use it inside U Master PE!

1: ESD decryption
(Warm reminder: In order to improve performance, ESD decryption will directly modify the source file. If you have a collection hobby, please back it up yourself)

First start Dism and click File--> Format Conversion--> ESD Decryption

Select the ESD you need to decrypt

Existing known decryption keys will be automatically matched, which means that the key does not need to be entered by yourself. Of course, dism must be updated at any time to prevent new esd images from appearing, resulting in the inability to match the key and unable to decrypt successfully. !

OK Done...
Now you can do whatever you want with ESD, Dism provides complete ESD support, including ESD to WIM! (Warm reminder: You can directly modify the ESD when opening the image file)
