    New HDD, broken MBR (no bootable device found)

    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?

    Windows Boot Manager might be in your old HD. Re-connect your old HD and set it to the first boot device in BIOS to see if it will boot again. If succeeded then download: EasyBCD Portable | Portable X Apps. Run it, and follow the screen shot to move the Boot Manager to C: drive (SSD), disconnect your the old HD then try to reboot again.

    NOTE: From the screen shot, replace Z: to C:

    It looks like you have set the first partition on the SSD as active. I assume this is the Windows install.

    That being the case, removing other drives as topguncp suggests is always helpful, but it may take 3 runs of a Startup Repair to replace the boot files in that partition. Since this is Windows 8, the Startup Repair option is, I believe, in the second occurrence of an Advanced Repairs option in the Recovery options.

    Or, you could make sure what the OS partition drive letter is and use the command below. You need to use the correct drive letter for the Windows partition, and in the command, I will assume it is C: but use what you show.

    bcdboot c:\Windows /s C:
