This is regardless if the installation has been dual-booted or not. The problem appears to be the AHCI module. Hardware: Intel i7 980x processor MSI Big Bang-XPower motherboard XFX HD-485X-ZNFC Radeon HD 4850 video card DDR3 2000 ram (16GB) >How-To-Repeat: FreeBSD does not have AHCI enabled by default, however, PCBSD does. In the loader.conf file, ahci_load="YES" will cause the problem to occur. >Fix: In the loader.conf file, ahci_load="NO" allows normal startup. This problem was addressed in the (long) thread: http://forums.freebsd.org/showthread.php?t=20724 And in the PC-BSD forum: http://forums.pcbsd.org/showthread.php?p=85036#post85036 >Release-Note: >Audit-Trail: State-Changed-From-To: open->feedback State-Changed-By: gavin State-Changed-When: Sat Jul 2 22:08:02 UTC 2011 State-Changed-Why: Hi, Sadly, from what you've provided it is pretty hard to figure out what has gone wrong. Do you have a way to capture the boot messages? Once at the ROOT MOUNT prompt, if you hit scroll-lock you should be able to scroll through the previous pages with page-up. Is it possible for you to take a digital photo of each page and upload them somewhere?
