Hey,

I have currently have a samsung 840 pro 120gb, and today I added a samsung 860 evo 500gb, but now the current SSD will not boot.

I have tried the SATA cables, and even taking out the new SSD and putting it back the way it was, but even with that the old SSD will not boot.

I have also checked the boot priority to no avail, and used the windows 10 startup repair with no success. and finally figuring that the old SSD had somehow died during the installation of the new one, I installed windows 10 on the new SSD, and the files on the old one are still there and accessible.

Is there anything else I can try to get it to boot from the old SSD? I had only planned on using the new larger one as storage for some games, and keep the old one as my OS drive.

Thanks,

Solution
So your system is booting from D: drive. Bootloader is located there (120GB - description "System").
OS is installed on C: (500GB drive - description "Boot").

And you want to be able to boot OS from D: drive.
Ok. If OS on D: is not corrupted, that can be done:
  • Open elevated command prompt;
    run command
    • bcdboot d:\windows /s d:
Next tome you reboot, there will be multiple OS boot options - one for booting from 120GB drive, other for booting from 500GB drive.
They will be named the same though.
You can edit descriptions of those boot entries with bcdedit command.

That means you didn't run the command from elevated command prompt. Regular command prompt doesn't provide you with necessary permissions.

Right-click on start button and choose "Command Prompt(Admin)".

Thanks for clarifying that, It worked like a charm, thank you very much

So I should be able to format the new SSD and just use it as a storage drive now in the disk management tool correct?

Ok, I checked it without and it worked fine, so I reformatted, but it still prompts me to choose an operating system.

[strike]Is there any way to remove the second opetion?
[/strike]
Nevermind, I found it in msconfig and deleted the extra OS

Thanks very much for your help
