With Macrium Reflect, you would Image the whole computer (all drives, which will include all partitions). Type is Full, and write it to a file on an external HDD. Be sure to Enable "Verify after Creation". Also, create the Macrium Rescue Flash Drive and test it (be sure it boots then bail out). With those 2 things done properly, you should be able to restore not only individual files, but also (if needed) any drive that failed and had to be replaced. Even if it is the C-Drive (that is called a "bare-metal restore").
I need some advise on whether to Clone or Image my XPS 8930. It came with a 2TB M.2 PCIe NVMe SSD mounted on the motherboard. According to Macrium 8 free edition it has the following 6 partitions: 1. ESP (none) Primary Fat 32 LBA 150MB 77.6 MB used. 2.None Unformatted 128 MB 3.OS (C:) primary NTFS 1.85 TB 4.WINRETOOLS (none) Primary NTFS 990MB 498MB used 5.Image 9None) 14.77 GB 6.Dell Support (none) Primary- NTFS 1.30GB 837 MB Looking for advise as to Cloning or Imaging this drive. With all the problems the last year or so trying to install BIOS updates etc, I just want to know which would be the best to use to restore this drive if it comes to that.   Also, do I just use all the default settings in Macrium? I am not familiar with a lot of the settings it shows in the settings.  Any help/ideas would be appreciated. 
XPS 8930, Clone or Image?
