I screwed up.

I bought a new SSD (Samsung 850 EVO 500GB), installed it, and installed a fresh copy of Windows 10 on it. Now, my existing setup (Windows 10, 1TB HDD) won't boot. More specifically, when I choose the old HDD in my boot menu, it takes me to the fresh install. From there, I can access the files through Windows Explorer, but none of my programs show up under the Start Menu.

If I remove the SSD, the old HDD won't boot Windows at all. Startup Repair doesn't work, either.

How can I get my old HDD to play nice with the new install? My end goal is for my programs and settings to move over to the new installation and function as they did before all of this, while staying on the bigger HDD.

Thanks.

You could try EasyBCD to edit the boot menu and repair the boot files of your old hard drive, if everything is still there you should be able to make a dual boot work. You'll have to run it from the New OS if that's all that's working obviously.

Most programs need to be reinstalled to work on the new OS, you may, fresh install is best anyway. be able to then copy the old folder over the new one to transfer any settings & data but that only works sometimes as well. Just start installing stuff I say

This will not work.
The Registry (and other places) on the new OS on the SSD knows nothing about those. You can't just move them into the new OS.
