[ubuntu] Win7 does not boot after 12.10 dual boot installation

view story

http://ubuntuforums.org – Hi all, I'm new to Ubuntu and I've installed Ubuntu desktop 12.10 in my Satellite L300D, alongside with Win7. While the Ubuntu installation seems to be just fine, I can't boot Win7. When I choose the "Windows 7 (loader) (on /dev/sda2)" it changes to a black screen for 1 second and then it returns to GRUB. I've tried the Boot Repair solution but it didn't work. This is my Boot Info: http://paste.ubuntu.com/1371004/ Can you please help me? Please tell me if you need further information about my settings. Thanks and regards! (Hardware)
