are installed with following steps , they are producing bootable and very
well working systems :

When the same steps applied to the following installs :

FreeBSD 10.0 amd64 Stable ( 2014-06-30 , r 268 038 , .iso ) ,
FreeBSD 10.0 amd64 Stable ( 2014-07-12 , r 268 571 , .iso ) ,

FreeBSD 11.0 amd64 Current ( 2014-08-04 , r 269 497 , Disk 1 , iso ) ,

the installed systems are not bootable , and the last sentence on the
screen is the following :
