BootMGR is missing - how to make SSD bootable without formatting

So, I've got a situation. I bot a new SSD and cloned the original HDD to it with the samsung migration tool. What it didn't tell me is that there will be problem in booting.

So I ended up with both disks throwing errors that Bootmgr is missing. I tried my best to fix but nothing worked. I reinstalled Windows on the HDD but still have the SSD with all the data and files that is unbootable due to the bootmgr missing. My question being, how can I make the ssd bootable without losing data?
