Note that the Active flag isn't stored in the boot code, but in the partition table. When you create the FreeBSD slice in the MBR during installation, it will have the Active flag set. You can manually reset the Active flag on the Windows partition before exiting that stage of the disk editor and things should work as expected. Would you be able to try that out and verify that? =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
