[ubuntu] No bootable drives after Ubuntu Dual-Boot with Windows 7

view story

http://ubuntuforums.org – I tried to install Ubuntu 12.04 on my new ASUS k55a laptop today, and somehow managed to lose access to all partitions on my computer. I tried boot-repair and reinstalling ubuntu but it's not helping. When I try to turn on my computer after the installation, it says to "Reboot and Select Proper Boot Device" on a black screen. In BIOS, there's no noticeable bootable options aside from the disk drive (I'm on Ubuntu Live CD). I'm not completely sure what to post here, but I uninstalled all my partitions except the two windows partitions (OS and Recovery). What new partitions do I need (Hardware)
