I use Paragon Hard Disk Manager 15 Pro I receive a warning when attempting to a delete copy of a partition on an external HD. The external HD is one I just made copies of partition to for backups. This external HD is not set to boot from. After selecting to delete a backup partition on external drive I get this warning. "Are you sure you want to delete active volume (G)? You are about to delete volume (G) Windows8_OS. NTFS. Your computer may no longer boot or work correctly." Please enter the volume label to confirm deleting...Yes / No. Is deleting this copy from the external HD going to damage my computer so it does not "boot or work correctly?" After I abort deleting partition. I attempt to set the partition copy on the external drive to Inactive. I get this warning "Are you sure you want to set the volume as inactive? You are about to set the volume (G) Windows8_OS. NTFS as inactive. You computer may no longer boot correctly." Yes / No. Can I delete this backup partition on the external HD without affecting my computer? Should I set the copy to inactive first? Basic info about partition copy on External Drive: Type Primary File system:NTFS Partition ID:0x07 NTFS, ExFAT, ReFS NTFS version:3.01 Active:Yes Hidden:No Thanks for any information. I would think I can do what I want to the eternal drive without affecting my computer.
