I'm about to set up my new computer....I got a SD card reader for it....Should I install this after The setup is complete, or go ahead and just add it as I build it...
likely won't make a diff. On the other hand you have a choice. let it go and finish one at a time. as ya reboot you will likely know where the issue was.
say another way i install maybe an operating system then boot. install a hardware then boot and do again as needed.
You may as well put in the card reader now. Tremmor has somewhat of a point, but chances that the card reader will keep your computer from booting are rather slim.
