[ubuntu-ar] la instalación ubuntu no carga el mbr en dualboot y winloader solo abre el w$7

Estimados,
recurro nuevamente a la solidaridad de esta lista porque ya he dado
tantas vueltas por google y demas lugares y no he podido resolver la
situación.
En el trabajo se ha comprado una pc nueva con win$ 7 home premium 64 y
si bien la pc la usaré básicamente yo es una pc compartida. Yo soy
usuario de ubuntu hace años y  quiero instalarle el ubuntu 12.04
manteniendo el w7 para el resto de usuarios de la pc. pero
lamentablemente una vez hecho el proceso de instalación  sigue
arrancando directamente el w7.
La maquina es una Bangho con placa gigabyt H61M-S1 y procesador core
i7, tiene un disco de 1tb y 8gb de ram.
Me dirán porque no saco w7? pues bien, porque no hay una política (ni
intención) en el trabajo de poder hacer el traspaso a linux, y segundo
porque suelen usarse software que aun teniendo homologo en linux no
están dispuestos por el momento a cambiar o dejar la comodidad de lo
aprendido. Sin embargo para mi es esencial tener ubuntu instalado
quizá por las mismas razones que ellos no quieren pasar a linux.
Siguiendo con el promblema comento lo que hice:
De fabrica la maquina vino con un disco de 1tb y con 3 particiones
ntfs nombradas system (sda1), recovery (sda2) que esta oculta y sda3
como OS que ocupaba el resto del disco. Redimensione esta última y
cree una partición extendida (no me dejo crear mas de 4 primarias a
pesar de que supone tener UEFI). con 3 particiones (raiz, swap y home)
y deje el resto libre para crear en el futuro una partición de
almacenaje de datos.
Luego de varios intentos y de googlear, intente cargar el grub
manualmente y nada.
Me hablaron de modificar el arranque con bcdedit pero no lo hice
porque no tengo mucha idea, pero además, desde ese no me reconoce
(lee) el resto de particiones linux no me aparecen con letras o nombre
como para que yo pueda asignarles en el bcd donde buscar, o sea que no
se como modificar.
Bangho no se hace responsable y no brinda soporte técnico para linux
(la $$%#$#), en el lugar donde la compre (que son dealers de bangho)
me dicen que tengo que modificar el archivo de arranque ídem lo
anterior.
La mas fácil sería formatear todo y volver a instalar, pero resulta
que como es OEM pre instalado, no te dan el cd de instalación del w7
lo que hace que pierda la licencia, lo cual no creo que ponga muy
contentos a mis jefes. Si pueden darme una solución menos traumática
les agradecería.
Abajo paso lo que tira con  fdisk -l  y lshw
Disculpen lo largo del mensaje pero quería ser lo más claro que puedo
en explicar el problema.
un saludo a todos

PD: este correo lo mande el viernes que estaba con la máquina en
frente, reenvío ahora porque no habían entrado. Obviamente hasta el
lunes no podré probar las posibles soluciones pero agradeceré las
mismas para ir viendo como hacerlo.
