During installation, when you are asked to edit the disklabel, the installer is going to erase every partition you define in preparation for installing OpenBSD onto your new empty partitions. If you want to keep a portion of the disk untouched (e.g. because it had data from before that you will want to continue to access later) what you need to do is leave that space unallocated, then after OS installation is completed you can edit the disklabel to define the additional partitions. TL;DR - when you are at the disklabel step in the installer, you are not being asked to declare partitions you want to keep, you are being asked to define partitions that you want wiped clean in preparation for your new OS install. -ken
