Wrong partition for windows 7 in dual boot

I did a wrong partition and I would like to remove and reinstall seven on the right partition.

but for this I must also remove the dual boot create during installation how?
I know I must find the boot.ini file that I made under xp ? I know I've already been there a long time.

If some can help me Get there im to confuse ?

You can edit the boot.ini to it and delete the line. If you cut and paste its contents here, we will tell you what to do

Warning: Boot.ini is used on Windows XP and earlier operating systems.
; Warning: Use BCDEDIT.exe to modify Windows Vista boot options.
[boot loader]
timeout = 10
default = multi (0) disk (0) rdisk (0) partition (1) \ WINDOWS
[operating systems]
multi (0) disk (0) rdisk (0) partition (1) \ WINDOWS = "Microsoft Windows XP dition familiale" / noexecute = OptIn / fastdetect

OK, you do not happen like that, then. Use VistaBootPRO.
