Dears All ,

When

FreeBSD 9.1 amd64 Stable ( 2013-04-28 , r 250 009 , .iso ) ,
FreeBSD 9.2 amd64 Release ( .iso )

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

Install
Partitioning : Guided ,
Partition : Entire disk
Partition Editor : Finish
Confirmation : Commit
Final Configuration : Exit
Manual Configuration : No
Complete : Reboot


When the same steps applied to the following installs

on the SAME computer   and HDD  <-------------------------------------

 :

FreeBSD 9.3 amd64 Release ( .iso ) ,

FreeBSD 10.0 amd64 Release ( .iso ) ,
<-------------------------------------

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 :


No bootable device -- insert boot disk and press any key

.


I have applied the following steps to make the

FreeBSD 10.0 amd64 Release

installation bootable :


I have booted the computer by the Release DVD ,
from the "Install Shell LiveCD" , I have selected "Shell" , and
entered

gpart set -a active ada0
reboot

with respect to advise giving in

The installed system booted successfully from the HDD .





Thank you very much .
