Solved: Have Winxp added second HD with Win7

I have a Dell Dimension 9100 with WinXP on it, so I got HD with Win7 on it from my bro's computer who's processor went bad. Both are Sata HD's

I swapped the cables from the XP HD and put them on the win7 HD and then plugged the power cord and data cord for the old HD and put them in the Sata 1 spot.. So now I have the win7 HD in the Sata 0 spot and the old HD in the Sata 1 spot..

When I turn on computer, it first tries to boot up and I can see the win7 screen try to load then it stops and thats when I get the error message Windows Error Recovery do I want to Launch Start Up Repair, so I say Yes, then It say's Cannot Fix Problem and say's Problem Signature..

Help...

Note: I went into the bios and it shows both HD's, win7 first and winxp next.. If that helps..
