I installed Ubuntu-12.04 (LTS) through a USB drive and when it's done i cant load Windows 7 (Loader)(on/dev/sda1) in GRUB. When I select that, it displays a black screen and then returns to GRUB but i'm still able to boot into 12.04.

Help me to solve this, I installed Boot-repair,I checked reinstall grub in the main option tab and checked place boot flag on sda1 windows7 in other options tab , re booted and it wasnt working this is was bootinfo summary http://paste.ubuntu.com/1206875/,

i also tried sudo grub-install "(hd0)" sudo update-grub in the terminal and i gave me found Windows 7 (loader) on /dev/sda1 and rebooted but i still wasnt able to boot into windows 7, this is my bootinfoo summary after i typed those two commands http://pastebin.ubuntu.com/1206955/

please help me,I'm at wits end thanks Dimeji
