Cant boot from anywhere

Hi, i'm stuck with a problem on my Mac.

I have installed the windows 7 through bootcamp and it worked fine until when i realized that i was needing more disk space on windows. I searched on Google and found some instructions. Here is what i did:

Resized the OS X partition in disk utility.

Booted on windows and tried to resize it partition in the native disk utility without success.

Searched for a program to resize partitions. I found one that i dont remember the name but i installed it and it told me to restart the computer to complete the installation, so i did. But when windows was booting, it showed a blue screen and restarted. I tried some options like safe mode and last valid setting but without success. So i realized that the message in the blue screen was: unmountable_boot_volume.

I had spent ali the day trying to fix this, but seems like impossible. When i press alt on initialization, it only show the windows option to boot. Also tried the recovery mode of OS X, had to wait like 40 min. to download the recovery mode and when finished it was helpless. The disk utility didnt enabled the option to repair my disk. I have the usb pen drive that i used to install windows but when i try to run the recovery mode from windows, it dont recognise my keyboard and my mouse, tried external ones and Also didnt worked. So, Mac OS wont boot, windows wont boot, recovery wont help. Anyone have a guess? I'm really stressed with it!
