Thanks for the error report!

In this particular error, the MBR doesn't seem to have anything to do 
with it. The real error message is in the logfile here:

Running: umount /dev/ada1s2a
umount: unmount of /mnt/boot failed: Device busy
EXITERROR: Error 1: umount /dev/ada1s2a

I'm trying to duplicate this, but haven't been able to so far. The 
second time you loaded the system, did you have xterm open or anything 
running in /mnt while the install was going?
