I have been running W7 on my hack PC and now I would like to try it on my current PC. I have 2 SATA HDD's fitted - (C) and (G). I would like to install W7 on to (G) as a fresh install (there is nothing on (G) I want to keep). I think I can go about the installation but I am wondering how the dual-boot system works? Once installed and on PC boot, will I be given the option which system to boot? Thanks.
