Forget this. It turned out to be a simple "space chooses the item". Looks like the other installers, the option was pre-selected, hence the confusion. 24.7 with ZFS is now installed and I am going on with the updates and other configurations.
I finally decided to go for OPNsense and have done one router with 2.5Gb ports. Installation went fine.
Then I decided to do it to my router that is around 2 years old. 8GB RAM, 64 GB SSD M.2
The installer is not able to find the correct drive. I have even gone back to an old installer, but the same.
I previously had pfSense+ on it with ZFS. Ran absolutely fine. But as I from now on will stick with OPNsense, I want all of the other over as well.
I have no idea where to even begin looking for a solution. This is so atypical... Should I use Gparted to erase previous data? Is there a partition that OPNsense prefers?
If the drive is not detected then your HW is probably is not supported by FreeBSD 14.1. GParted will not help.
Problem already solved. Read solution in the text above your answer.
Thank you for replying.
