Effective Solutions to Resolve the Error

Step 1: Format the EFI System Partition to FAT32

Begin by noting the size of the EFI system partition. During the Windows installation, you can see this partition’s size, which will guide you in identifying it correctly.

At the Windows installation screen, press Shift + F10 to open the Command Prompt. Type Notepad and hit Enter. This opens Notepad, where you can navigate to File > Open to enter the File Explorer through the installation interface.

Look for the EFI system partition by its size. Right-click on the appropriate partition, choose Format, and select FAT32 as the file system. Be cautious while picking the partition to avoid data loss.

Pro Tip: Ensure that you back up any existing data on the partition before formatting it.

After formatting, close Notepad, File Explorer, and Command Prompt. Then, click Refresh on the installation screen to continue installation.

Step 2: Remove Existing Essential Partitions

If your disk consists of multiple partitions, including System and Recovery partitions, consider deleting these to clear the way for a fresh Windows installation. Highlight these partitions on the installation screen, select each key one without a drive letter (usually appearing as small sizes), and delete them.

This action will create unallocated space on your drive. To proceed with the Windows installation, select this unallocated space. The installation should now proceed without errors.

Pro Tip: Check for any data or setups in the partitions you plan to delete to avoid unintended data loss.

Additional Tips
