This is also an issue when you’re using the System Center Configuration Manager from Microsoft, in order to reinstall Windows on a device, which is frustrating due to the number of users having this issue. This happens regardless of the Windows version you’re trying to install, and on both laptops and desktop PCs. There have also been cases where users reported this happening when BitLocker is activated, but for those who need it, disabling it is not an option and they need another solution. Fortunately, there are a couple of things that you can do to solve this partitioning issue, after which you can go ahead and install or reinstall any version of Windows you need. A universal tip before you go to any of them, however, would be to disconnect any other storage devices from your computer, as they may be confusing the BIOS and that might be the reason it’s failing.

Method 1: Set the boot options to UEFI

There are some devices which go to a BIOS boot by default, and that is causing them to give you this error, and fail to install Windows. Fortunately, the solution is fairly easy, and the steps below will help you even if this is the first time you’re entering the BIOS.

Method 2: Switch the drive controller to AHCI

This method will help you if for any reason, your BIOS controller is set to anything other than AHCI, such as SATA or RAID if you have multiple hard drives. Given the simplicity of imaging Windows from a USB or a hard drive compared to a clean install, it is no surprise that a lot of users have opted for this step. It is also much quicker, and therefore more efficient when trying to install Windows on multiple devices at the same time. If you’re having this issue, follow the steps above to solve it, and you will be able to continue with the process.
