what windows version?


Let me clarify. If its windows XP, it has to be installed on the computer you want to use. IE, you cant install it on one computer then swap it to another.
If windows XP detects a change in motherboard, it will NOT run, you can call up and get some code or something by telilng em you just switched motherboards, but considering you already formated, you just need to format it on the computer you want to use then install XP.


So, put the HD back in your computer, put in the XP CD, then reformat and install XP.
