Windows 7 messed up my bootloader? -

i have a multiboot system (xp/vista/seven/ubuntu/leopard) my (vista) bootloader is the bootloader i use and it worked fine with my xp/vista/ubuntu/leopard setup today i installed windows seven and it deleted my bootloader. i figured this would happen.. so i popped in the vista cd went to repair and repaird the vista bootloader rebooted and i went to my regular bootloader screen and to my surpise it added a new option (Windows 7 Ultimate (Recoverd) well how convienent.. vista added that for me.. thats so nice.. orso i thought i booted into seven installed Easybcd (bootloader editor) changed the name of Windows Seven Ultimate (Recoverd) to Windows 7 rebooted no bootloader found... eff.. pop in the vista cd go to repair and it detects no problem with my startup gt;.gt; so now the only way i can get into my system is to tap F12 and manually select the hardrive with my bootloader on it.. any suggestions? it would be much obliged..
