Remove EFI system partition from the disk space.
Hi, your harddisk still has the EFI system partition left after installing Windows for data use. The Disk Manager option to delete it is disabled. You've tried DiskPart and the Windows Installer, both showing issues. You might need to check the partition table or use a different tool like CHKDSK or third-party utilities.
The system has a flexible dynamic disk setup. Avoid modifying partitions directly; focus on managing volumes instead. You’ll see the available volumes listed, making deletion possible. There’s an unusual behavior where Windows mistakenly identifies the main volume as a page file.
The issue occurs across all drives due to virtual memory being activated. It's because Windows 10 with a Windows 7 skin is using EFI volume settings, not standard Windows 7. The EFI volume shows up in DiskPart, but the second recovery partition isn't listed and can't be deleted, causing the error.
