[QUOTE="bbnck, post: 1768444, member: 384434"] Take a full backup with Time Machine or a suitable alternative. Then open Disk Utility and select the drive from the left-side - the label of the primary drive usaully starts with APPLE SSD or Fusion Drive. With the correct storage device selected, click the [B]Partition[/B] button at the top of the window and select the partition you installed High Sierra on. With the partition selected, click the minus button below the item to delete it. It is physically not possible to delete the partition you are currently booted into, so don't worry about that. Note: If the [B]Partition[/B] button is greyed out, that's usually because you've selected one of the partitions of the drive and not the drive itself. [/QUOTE]
