Booting from USB

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
(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
