I've recently replaced my secondary HDD in HP Pavillion dv7 (primary is SSD@W8.1) and as soon as I booted up computer, I got error "no bootable devices found". The first thing that I tried out was bootable USB with Windows 8.1 whereas I ran "automatic repair" several times, without any luck.
 
Then I opened up command prompt under advanced menu and ran:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
 
None helped, probably because of "element not found" error. I also tried with diskpart where I manually selected (see screenshot) SSD system partition for active one, but still without any luck.
 
I'm really out of ideas, nothing seem to work. I also created bootable Minitool Parition Magic USB and ran Rebuild BCD from there and it still didn't help.
 
What else could I do, this is really frustrating?

If the computer has UEFI, it will not boot if the second hard drive has an extended partition. Does your second hard drive have logical partitions?

On one image the Windows OS is on F: and on the other image it shows it as on D: I am not sure why that is.
