So basically im bouta build a new computer, new case, new gpu, new cpu, new almost everything except the storage, that is a HDD that I store games on and a SSD which my windows os is installed on right now. (I'm using a desktop that I've played with for years at the moment I type this) I was wondering that if I was gonna boot my new pc on the SSD, is everything gonna just open fine and normal like it was my old pc or I gotta format it all and re-install windows from a usb key?
