I recently bought a Samsung 850 Evo 250 GB SSD for a newly built PC a few weeks after the build. I had Windows 8.1 Pro installed on the HDD. I then upgraded to Windows 10 before installing the SSD. The system booted up fine with the HDD. I then backed up the entire system to an external hard drive. After upgrading to Windows 10 and backing up the system, I used Samsung's Data Migration to clone the HDD to the SDD (I have used less than 200GB on the HDD). After the cloning was complete, I restarted and opened the boot menu and tried to boot from the SSD. I booted from the Boot Manager associated with the SSD and thought it was booting from the SSD. After this I formatted my old HDD, clearing everything from it. I soon realized I had booted from the Boot Manager and not the plain SSD listed. I then tried to boot from just Hard Disk: Samsung...(not the Boot Manager) and it says "missing operating system". I've tried to search for damaged or corrupted files through command prompt and it found no problems. I tried using Microsoft's Media Creation Tool and "upgrade this pc" and that didn't solve the problem either. I'm currently using Media Creation Tool to install Windows on a USB to try a repair install. Does anyone know a solution to this problem that doesn't involve a clean install and losing all my apps? Also, could the backup from the HDD to the external hard drive be restored to the SSD to fix the problem? Sorry for any ignorant descriptions. I'm new to this, it's my first build.

Few things
1) Are you using a UEFI boot because it sounds like it
2) The samsung migration tool sucks honestly. Most of us here use Macrium Reflect Free for any kind of cloning.
3) You said your backed up windows 10? If it did a system image then yes we can restore from that hopefully
4) we could use Macrium Reflect Free rescue media to fix windows boot issues but you need to install it on another PC and make the USB/DVD needed.
