I got all the parts to start my first build except for my ssd which will be for my oe and some programs. can I put the rest of the pc together and boot up bios with just the hd connected to make sure everything else works? Or will that start putting info onto my hd and screw up a clean build? do I wait to install the oe until the ssd is connected and the hd is disconnected? Or can they both be connected?
