    Fix bootloader from LiveCD

    My laptop fell off a table. Not far but it fell. I tried to boot up but I have the HDD pasworded and it couldn't get past that into GRUB, just kept looping back. I dual boot Win/Ubuntu12.04. I loaded a LiveCD I had of Debian and can access all my files without any error. I was going to attempt the boot-repair-disk from the USB, (making it with netbootin). I was wondering of there was any way just to fix it from the LiveCD I already have in and when you be involved with that? Thank you in acvance!

    You can chroot in to the installed system like this

    Code:
    * Open a terminal and type
    
    $ sudo fdisk -l
    
        * Now, you need to remember which device listed is your linux distribution, for reference, /dev/sda1 will be used. Now we need to mount the filesystem to /mnt
    
    $ sudo mount /dev/sda1 /mnt
    
        * Now mount the rest of your devices
    
    $ sudo mount --bind /dev /mnt/dev
    
        * Now chroot into your system
    
    $ sudo chroot /mnt
    From there you can start applications as part of the installed system and fix the bootloader etc..
