You probably found this article because you kept on getting a Windows Loader error when trying to activate Windows 7 on your PC. Before you try to learn how to fix the Unsupported Partition Table error, there are some things you should know.

The primary reason why anyone has to deal with Windows Loader is that of a bootlegged version of Windows 7. There is no other use for this software program but to activate the operating system without using a license key. Keep in mind that using a pirated Windows OS is intellectual property theft, and it has legal repercussions. What’s more, it can cause a host of issues and prevent you from enjoying valuable security patches and updates.

Why do I Get the Windows Loader Unsupported Partition Table Error?

It is not uncommon for people to pirate Windows 7, especially since it is quite easy to find third-party tools for superseding the license keys or the Windows Activation process. There was also a time when Microsoft willingly let users with bootlegged versions of Windows 7 upgrade to Windows 10 without spending a cent.

Keep in mind that variations of pre-activated Windows 7 are likely riddled with malware. Before you go for this option, you must be prepared for possible system corruption and even data leaks. In order for you to skip the activation process, you will need to use either Windows Loader or RemoveWAT.

Windows Loader is a BIOS emulator that uses a string of actions to trick the operating system into activating without a legally acquired license key. Many users who tried to run it encountered the Unsupported Partition Table error. When this message appears, it means the Windows Activation Technology (WAT) detected the illegal activity and prevented it from executing successfully.


Resolve PC Issues with Driver Updater

Unstable PC performance is often caused by outdated or corrupt drivers. Auslogics Driver Updater diagnoses driver issues and lets you update old drivers all at once or one at a time to get your PC running smoother


Usually, those who want to learn how to fix the Unsupported Partition Table error use the RemoveWAT tool. However, we highly discourage you from doing this. Software programs like this are typically full of adware coming from dodgy sources. As we’ve mentioned in one of our blog posts before, criminals use tools like this to install malware on computers, allowing them to acquire sensitive data. They can use the information to steal your identity or wipe out your bank accounts.

What’s the Best Option for Me?

If you want a safe and convenient way to enjoy the Windows operating system, we recommend purchasing a licensed version. There are many benefits you can get from this option. For one, you can install all the security patches and valuable updates that Microsoft regularly rolls out. What’s more, you won’t have to deal with incompatibility issues, especially when you update your drivers using Auslogics Driver Updater.
