I have a system that dual boots with Windows 7 (64 bit) and Windows XP (32 bit); each OS is on its own hard drive. I want to reformat the Windows 7, deleting the OS in the process. What I'm wondering is where is the boot loader located? Is it on the Windows 7 drive (since it was installed after XP), and will I need to do anything special to have the system load Windows XP by default after the Windows 7 installation is gone? Will the system simply detect the old XP installation and load it without the bootloader?
