Can't Activate New Boot Drive

[sbr01]

Hello all. I've been using a Samsung 850 EVO 500gb as my sole drive without issue. Recently, I picked up a 960 EVO 1tb and wanted to clone my 850 and make the 960 my new boot drive. I downloaded the Samsung Data Migration Software and copied everything over without issue. However, once I went into BIOS and marked the 960 as boot priority #1, it wouldn't boot to windows, instead displaying the error message: "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key". I did notice that my 850 displays "Window Boot Manager: Samsung 850 EVO" in BIOS. Do I need to change something in Windows Boot Manager? How would I go about this? Any help is most appreciated.

When you booted the computer with the 960, after the migration, did you unplug the 850 HD? And, if the 960 boots up fine by itself, you have to reformat the 850 to remove the Windows boot and OS.

I did disconnect the 850, yes. However, I still get the "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key" error message.

Somehow the 960's boot partition never got marked Active; you might have to usb or dvd boot a disk manager to mark 960's boot partition Active; of course the OS partition should already be set to Primary. I'm thinking Windows install DVD's Startup Repair may be all you need to fix this common HD situation.

I don't have a disc but I used the USB drive I used to install windows and ran the Startup Repair, but it said it could not fix my startup issue. How can I get into the disc manager?

Okay I finally got it. The partition was there, but Windows had set the drive to being offline due to a signature conflict with the 850. I forced it online, restarted, and on the second restart I noticed I had an option for Windows Boot Manager on the 960 (entirely possible it was there after 1 restart, but I didn't notice). @RolandJS thank you for helping!
