During installation of vSphere 8.0 on my homelab’s Dell Optiplex 9010 I had run into this not so helpful error:

Error loading /vsan.v00
"Fatal error: 10 (Out of resources)"

Quick Google search revealed nothing useful, really. This article from VMware might be helpful to some. Unfortunately Optiplex has no such setting. In the end switching from “Legacy boot” to “UEFI” resolved the issue.

This other post might be worth checking out as well.
