Hello All, I'm not a crazy computer wiz, I've built a couple PCs and fiddled around with some programming but nothing major. I just got a new laptop, a Razer Blade 15, but I want to use it for work and gaming. I wanted to partition the drive into two sections, one with about 150gb of space for work (I don't need a lot because most items are in the cloud or very small), and another drive with the rest of the storage for gaming. When I boot up my laptop I want to be presented with the option to choose the gaming partition, or the work partition. Is this possible and can anyone point me in the right direction or let me know how to do this? It would be very much appreciated.
