    Unable to boot Ubuntu (Windows boots fine, using EasyBCD)

    EDIT by varunendra:
    * Not able to boot Ubuntu
    * Used EasyBCD after initial failure (post #11)
    * Boot-Repair did not help either. (post #17)
    ----------------------------------------------
    Original post:

    I have Ubuntu 12.10 installed and I'm using a wireless adapter, an Edimax 7811Un. The problem I'm having is grub isn't working, when I select Ubuntu in the boot menu, I'm met with grub> on my screen.

    I've read that my wireless adapter has had bugs with Ubuntu and installing it, however I downloaded the current drivers and attempted to install them to find this in the Terminal: Authentication requested [root] for make clean

    I looked up how to correct this problem on this site: http://www.r-statistics.com/2011/11/...-ubuntu-11-10/

    However, using the method mentioned here in attempting to correct my adapter, it doesn't work. I can only get into Ubuntu through the USB stick, booting it in 'Try Ubuntu'

    I believe if I can get Ubuntu to connect to the wifi I can fix the grub> issue I'm having. How do I correct the bug with my wifi adapter while having my current problem?

    Any help is appreciated, thank you!

    Get to your ubuntu install

    Open a terminal and do this

    Code:
    sudo update-grub
    Code:
    sudo grub-install /dev/sda
    Reboot without your USBflash drive

    Once it's booting up normally we need to see the result of this to help with your wireless
    Code:
    lspci -nnk | grep -iA2 net
    Unless your using a USB wireless dongle?

    It's a wireless dongle, just a USB chip I plug in.

    I tried the sudo update-grub and recieved this message: /usr/sbin/grub-probe: error: failed to get canonical path of /cow.

    So you were booting to an installed system with the aid of the USB, not booting to a Live session on the USB?

    I can't boot a live session, when I use the USB stick it simply gives me the options to use Memtest, test for errors, install Ubuntu or try without installing.

    EDIT: Ubuntu 12.10 64 is installed, would I have slightly better luck if I used 12.04 64 or switching to 32 bit? I only use 64 because of my RAM.

    Re: Ubuntu wireless not working.

    I'm sorry
    But to me it's not entirely clear if you can boot your installed system or not? At first I thought you could. But now I think not.

    If you can't boot the live cd?

    Is that what you mean?

    Because earlier you said
    I can only get into Ubuntu through the USB stick, booting it in 'Try Ubuntu'
    I think you need to get so you either just re-install over the top or boot to a live session and repair grub
