    Exclamation Dual Boot Menu Not Showing

    HI guys. It's my first time to actually install an OS other than Windows that's why I am very new to the Linux Stuff. I just installed Ubuntu 11.10 in my laptop (ACER ASPIRE 4755G) using a USB Pendrive. The laptop is already pre-installed with WIndows 7. When I restarted after the installation of Ubuntu the Boot Menu where your suppose to choose whether to run Windows or Ubuntu is not showing. It just runs Windows 7 instead.

    This is my RESULTS.TXT
    Code:
