Pretty much same setup but barebone and ACHI mode but exact same problem. Seems to be a common problem regardless of DSM version.

I'm stuck at this point, tried different bootloaders and different DSM versions, i have followed the video tutorial found in this tread. i have tried manual installs without success. the thing is, i have 2 HP Gen 8, one running Xpen 5.2, and the new one i'm trying to install 6.1 on. im open to any sugestion.
