i have a hp prodesk 400 g3 mt.  i try to install an os named freebsd10.3.  i am able to install it successfully , to active i need to reboot the system.  after the reboot  the machine says  " boot device not found ".

Whats the problem.?

New disk-drive, or "previously-used" disk-drive ?

Reboot the computer, and enter BIOS SETUP, and confirm that the disk-drive is the first item in the list of bootable devices.

Or, reboot the computer, and select "change boot devices", and select the disk-drive.

i bought the machine as new from hp . that 's to say i am trying to  install it as first. 

Does harddisk  has to be the first item on boot options? i see it in the boot option item lists. 

I move the harddisk item to the first row in boot option now.   

I will try again now and notify the case .

thank you

See: http://h30434.www3.hp.com/t5/Desktop-Operating-Systems-and-Recovery/Can-not-install-Linux-on-HP-Pavi...

for information about "Secure Boot" preventing several variants of Linux from being installed.

But i had set enable legacy and secure boot disable on the bios settings ( via F10).

1-) does the problem cause  GPT while installing on the sata disk?

2-) is there a installations cd for  prodesk 400 g3 mt ?   there was for proliant.

secure boot  is already disabled.  But i realized that if the installation go on gpt of hard disk partition the pc will gives the error. i changed mbr instead of gpt, freebsd installed succesfully without any problem.
