Installing XP on secondary hdd (dualboot)

[MilkDrop]

Hey guys!
I'm pretty new to linux and am not fully satisfied with the performance in games I get with Wine so I'm thinking of installing XP on my storage drive (ntfs). I just wanted to know if it is possible to install windows after installing linux and still dualboot, and is it possible to have the OS's on separate discs?
Could someone explain how I should do this?

Thanks in advance,
MilkDrop
