First partition is system, primary, NTFS, 0x27 Windows RE, 1.4 GB. Second partition is drive C:, primary,NTFS, 0x07 NTFS,578.8 GB. Third partition is not named, primary, NTFS, 0x17 hidden NTFS, 15.8 GB. I think that the 3rd partition must remain as the last one. So can I safely partition the C: drive without losing the recovery system.
