Macbook Pro 2011 13-inch not loading Windows SO (never SOs...) ¿Why?

Hi guys!

I have a great problem with my MBP 2011 and Boot Camp utilities... I need Windows to my job and the other tings. I tried install some Windows I have... Winws 7 x86 and x64, Windows XP... but it´s impossible mission

My Macbook Pro is modified:

- Core i5 2,3Ghz
- 8Gb OWC DDR3-1333Mhz
- 128 Gb OWC SSD (replacing superdrive)
- 320 Gb HDD (factory)

I have done the following things:

- Install Windows 7 with USB Key ---> nothing
- Install Windows 7 with external USB DVD Drive --> nothing
- Install Windows 7 used boot camp wizard of OSX Lion --> nothing

the problem is the same... When run and finish boot camp wizard reboot normally but the display goes black and installation dont continue... only blinking cursor "_"...

I dont find any solutions... I´m desperate puff

Ahh... I have installs rEFIt boot, but I dont think that influences, righ?

¿is it normally?... I don´t think...

Thx

PD: Sorry I´m from Spain and my inglish is a litte bad 🙂 I hope you undertand my problem 😟
