If you’ve dealt with Windows Loader, we can safely assume your tech guys are pirating the OS. There’s no other need to use this tool except for the activation for Windows.

We don’t support pirating Windows. Besides intellectual property theft, it might result in lots of issues, like Windows loader unsupported partition table error on Windows 7, and deprive you of valuable updates. 

What is an unsupported partition table error in Windows Loader?

Windows Loader is a common tool that is a part of MSToolkit software specifically made to activate Microsoft products, like Windows or Microsoft Office. It basically uses a string of BIOS-emulating actions to ‘trick’ Windows into activating.

However, some users who tried to run it were met with the Unsupported partition table error. This means WAT (Windows Activation Technology) detected it and prevented it from executing.

Below are some of the other potential causes of this issue:

  • Pirated Windows version – If you pirated Windows 7 to avoid activation, you are likely to get this error message. And that’s hardly uncommon, as a lot of users got used to some of the third-party tools to avoid Windows Activation or apply license keys.
  • Corrupted partition drive – In some cases, this issue might not just be down to pirating Windows 7 alone. It can also be caused by issues with the partition drive.
  • Disk format is not supported – At times, you can get this error because your disk format is not supported. This is especially through if your disk is formatted in NTFS and ReFS, which is not supported in older operating systems like Windows 7.

How do I fix the Windows Loader unsupported partition table error?

We won’t provide you with any links, but since you have gotten this error, you probably know about the RemoveWAT tool.

While this tool, will help you clear this error message, it is highly suspicious, and we do not support its activities.

There is always a possible malware presence in all those pre-activated Windows 7 variations circulating online. Add possible system corruption after update installation, and you’ll think twice before going for it.

With that in mind, most software pirates will install a standard version, skip the activation, and use either Windows Loader or RemoveWAT tools to activate Windows 7.

Keep in mind that these tools are usually full of adware and come from suspicious sources, to say the least. With this tool, you should be able to activate Windows 7. Again, there’s a good chance that something will go wrong, so act of your own volition.

The safest approach is to use a genuine Windows OS version.

With that said, we can conclude this article. In case you have additional questions, feel free to tell us in the comments section below.
