Upgrading SSD from Samsung EVO 840(256GB) to EVO 860(1TB) - Disk Issue
I wanted to use bootcamp to run windows 10 and MacOS high Sierra. So I proceeded to purchase a storage upgrade from 256GB to 1TB SSD. I followed the attached videos to format and download macOS High Sierra to my 1TB SSD through an external SATA III connection:

Upon formatting and installation, I proceeded to turn on my Mac, but the original SSD (EVO 840 - 256 GB) was the only disk showing under disk utility ( See attached picture) even when its the new 1TB currently inside the MacBook Pro.
I couldn't boot into the 1TB SSD initially after changing the SSD, so I decided to reinstall MacOS High Sierra into the 1TB drive through recovery mode (While it was still installed in the MBP) in hopes that 1TB drive partition would be recognized upon installation.
I was able to complete the installation but when I opened disk utilities it still showed the old EVO 840 name and partition size.
I also tired clearing the VRAM, PRAM and SCM and it still showed the old SSD info and the portion size as 250GB.
I suspect that maybe the EVO 860 might not be compatible with this model but I researched many reviews that mentioned it would work.
Not sure what to do to get the MacBook Pro to recognize this 1TB drive, any tips or help would be greatly appreciated.
