I assume your portable SSD is connected to USB and you most probably use a USB pen drive to install as well. What often happens is, that your installation pen drive is /dev/da0 while your portable SSD is /dev/da1 during install. So the installer will add an entry to /etc/fstab that /dev/da1 is where the system should boot from in the future. Now you reboot and remove your pendrive. With the pendrive gone, your SSD will now be /dev/da0, but it tries to boot your newly installed system from /dev/da1..., since that's what in /etc/fstab. You could either drop to the shell after install is finished and fix the entry in /etc/fstab before you reboot and exit the installer, or... Reboot the machine, and when loading fails, at the loader prompt tell the loader something like > UFS:/dev/da0p2 (may be da0p3, depends on what the installer did. in FreeBSD one can type "?" to list devices. I've never used Trident) Then when the system is up, fix /etc/fstab entry from e.g. /dev/da1p2 to /dev/da0p2 Am Sonntag, den 09.06.2019, 17:04 +1000 schrieb Anders Jensen-Waud: > On 9/6/19 2:48 pm, Brian Wood wrote: > > I installed Trident onto a portable SSD.
