Ok so I originally have windows 7 rtm and i liked it but i wanted to boot windows xp so i made a new partition and installed xp on that. After the instalation it just booted up in xp and didn't give me an option to boot windows 7 or xp.
Its because u installed XP after u installed windows 7. XP doesnt understand the coding for 7 therefore u cannot integrate the 7 into XP bootloader. ITs pretty simple fix as kemical has described in the fact that all you have to do is put in the seven disc and boot to it and choose repair then repair startup. It should then detect the XP partition and Add it to the bootloader.
