I have a HP T620, and installed OMV correctly a long time ago. I used the method described in this post, and that worked previously. However, last week I decided to upgrade the ssd with the OS, so I reinstalled OMV, but this time if I copy those directories I still get the error that it can not find any boot drive. For now I have been booting using the refind usb stick, but that does not seem ideal. Does anyone know what could be wrong?
EDIT:
The instructions did work, but the boot order was completely wrong which I did not expect (the previous time this did not happen)
