Windows Vista 64 bit dual with XP.

My Windows Home 32 bit computer crashed and I bought a Windows Vista Home Premium 64 bit to replace it not realizing potential compatibility issues. (OEM installed OS no disk, no recovery disk came with computer).
1. I would like to purchase XP 32 bit OS and install it on a reformatted 2nd HD which I installed in the new computer already. I can't find a guide anyplace to help me install this that doesn't require re-partioning the OEM HD or that doesn't require the Vista CD.
2. Since I have a device (SkyCaddie Golf GPS) that is not compatible with 64 Bit system and I use it regularly, I need a 32 bit OS.
Can anyone make recommendations and provide me a solution?

 

Dave,
Thanks I did read them and everything I read or was referred to through the threads talked about "shrinking the Volume" on my HD and not using a separate HD. So I was looking for some help installing XP 32 on a Vista 64 Bit Computer using a separate HD. Also, in deciding what XP to buy, there are versions out there that require installation on a "Clean" hard drive. If I can't figure out how to install on a separate HD will I be able to install that version on my Vista HD?
Thanks for the feedback

 

Dave,
Thanks for the feedback. I have located a procedure and once I have completely absorbed it, I will install the XP OS, I am going on a trip so have decided to wait until I get back to do this, since I want to focus that task alone. I will let you know how I do in a couple of weeks
