New OS on a second HDD.
I currently have a 160GB internal HDD running as my primary but I wanted to purchase another HDD and install another OS on it (don't want to bother with partitioning the darn thing.) I wanted to know what things will I need to be aware off before I can successfully install a OS on this new HDD? Will I have to make the new HDD my primary HDD temporarily etc.?
Thanks in advance for the help.
