I recently received a 64GB SSD as a gift, and I was thinking of using it as a boot drive. The only issue here is that I have already had the computer I plan to use it in for about a year and a half. The 2TB HDD in it is full of my stuff, and I am confused on how to make the SSD my boot drive without messing up how all my programs I already have installed. I know I have to do a clean install of windows in order to make the SSD the boot drive, but I am highly concerned about my computer still being able to function. In short, how would I go about making the computer boot from the SSD and still be able to use all of the programs and files on my HDD?
