Booting Vista

Hey there, i went from XP to vista, and did a reformat, Or what i thought was one as it happens now when i boot, i get the option to boot from Vista or "other Version of windows" which in my eyes makes no sense, i have look at the disk management and there is nothing in there other than vista, and i checked the boot.ini and it only has "current OS, Vista OS". Be glad if anyone could help me out. It more of an annoyance of having to hit enter everytime I boot up

Thanks
Adam

 

What happens when you try to boot the "other version of windows"?

 

When i click it, it comes with with an error, can't remember what, but as soon as i have wrote this post i will check and then reloads to the OS selection screen.
