Forgive me if there is a thread already, please refer me if so. I just replaced a 64gb SSD (my C: drive) with a 500gb SSD. My computer still shows the 64gb SSD (not even installed) but boots from the 500gb SSD that is installed. The install was accomplished with the included Samsung (came with SSD) software for cloning the old SSD to new SSD. Then after a series of issues including several bios resets, a pc repair shop a bios reinstall and a boot disk, the pc finally booted again. (There is more to this story too if you want an explanation) The big issue now is that after replacing the 64 with a 500 I still have no more available space to install my programs.
