hi I followd a tutorial on how to dualboot windows 7 and windows XP. basicly my PC has windows 7 and I shunk the C: drive. I then installed windows xp over the new partion. now I cant boot windows 7 becuase the boot manager won't show ( the one that says "selctet youre operating system": http://www.howinthetech.com/determining-if-your-computer-fails-the-memory-test/ (I am just showing this for the pic.) when I turn my PC on it goes straight to windows XP.

I know my windows 7 partion is still there it is on local disc I: it still has all the files intact I just cant boot into it. and I know my PC supports dual booting as it has before.
 
I allready tried editing boot.ini I get a black screem or a shutdown (I do see options and only windows XP works when I select. like I sied before if I use the 7 disc and choose the repair option I can get back to 7 and when I want xp I have to do the same but with the xp disc. I also read in windows 7 it says "Use BCDEDIT.exe to modify Windows Vista boot options" and xp uses boot.ini.
