I built my brother a computer and included an SSD as the boot drive. When I built it I installed the SSD (around 120GB) first and by itself, then installed windows and everything else, once it was working I installed the HDD (about 2TB). My problem now is that the SSD is considered the C: drive and almost everything installs on that instead of the HDD, and the SSD is full now. Is there a way I can make the HDD the C: drive or the standard dive while keeping the SSD as the boot drive and keeping room for a few games/programs on there? Would it be simpler to just back up his files and 'start over' having both the SSD and HDD installed, and just have the SSD as the boot?
