I just bought an SSD for my computer and I would like for the SSD to be the boot drive and have my old HDD as mass storage, the problem is that the HDD has windows installed in it and I would like to keep the things that are in it so I don't want to format it, so can I use the SSD as my boot drive, use my other drive as storage and move files from one drive to the other even tho both have windows in them?
