PfSense not booting after install, waiting for F1

[hollister]

Board apu1c4, with 16GB SSD, Bios: April 5 2014
SSD: http://www.pcengines.ch/msata16a.htm

F1  pfSense

F6  PXE

without pressing the F1 key it will not continue.

PS: If I press 'F1' it works fine.

I found somewhere the following:

/sbin/sysctl kern.geom.debugflags=16
gpart set -a active -i /dev/ad0s1a ad0
/usr/sbin/boot0cfg -s ad0s1a -v /dev/ad0
/sbin/sysctl kern.geom.debugflags=0

but I get errors since my HD is ad4
gpart set -a active -i /dev/ad4s1a ad4        (gpart: Invalid value for 'i' argument)

any ideas

What happens if you try a reinstall to that hardware.

never mind, just needed to wait for 20..30 seconds and it continued to boot.
