Two os in one computer

Hi I have just built a new computer(the easy part), I have installed windows 7 onto the new terrorbite, I want to transfer user data from my old hard drive which used windows xp, I was thinking of installing old hard drive into new computer and keep running xp on that old drive and any new programs install to new hard drive. reason is because i purchased win 7 64 bit and I think some of my data from xp 32 bit will not be compatible. Will this work ok without to much complication or should I just transfer data to new hardrive and just replace programs that are not compatible, if I do, I would like to keep old hard drive as a 2nd hard drive. Hope I haven't confused anyone, I am not to good with software issues.

 

If it is jut pictures, documents, music, just place the old drive in a case and then take over "rights" of the drive. If you place it in your existing machine, make sure that it is set as slave, and that again you take over "rights" of the drive, in order to access those documents, photos, etc..

If they are programs, you are going to have to reinstall them on the new machine. There is no moving programs from an older OS to a newer OS, no matter how hard you try.

 

Thanks for your reply, I think what you have said seems like the clearer direction to take(simpler).
cheers
