Dual Boot Window 8 and Linux Grub FiX

Posted: November 6, 2012 in Linux


if Linux Grub boot loader is not coming after install window 8

than do following steps —


Insert Live CD (Linux)


go to terminal

insert all of these commands in root, or with sudo

mount /dev/sda5 /mnt/           ( in my case sda5 is the drive where Linux is already installed, to check this -- type "sudo fdisk -l " in terminal)

mount -o bind /dev /mnt/dev
mount -o bind /proc /mnt/proc
cp /proc/mounts /mnt/etc/mtab/
chroot /mnt /bin/bash
grub-install /dev/sda

restart and remove disk


  1. windows says that they have secure boot feature .. Unified extensible firmware interface (UEFI) instead of earlier BIOS … User will not be able to boot linux os on windows 8 PCs… So after applying this command should it load linux ???

    Hi abhinendra

    Short Answer is YES.

    you can run window 8 and linux in same PC

    following is my case –

    my Hp Elitebook 500 GB hard disk
    partitions details
    250 GB -for Window7 64bit (this is ntfs file system)
    10 GB – for Linux Swap
    240 GB – for Linux Mint 13 (this is ext4 file system)
    i am smoothly using both (Linux mint 13 and window 7 64 bit) in my Laptop.
    whenever i started my laptop it shows GRUB window and linux selections …etc

    then i decided to format window 7 partition (NTFS) and install window 8 .
    but want to keep my Linux as it is.

    i just insert window 8 bootable disk and format my ntfs disk partition. and install
    window 8 in that partition.

    window 8 is installed sucessfully 🙂
    but , after boot Grub (selection menu for linux is not coming) 😦

    than i inserted Linux Mint 13 Live DVD. and start linux live.
    and i follow this method

    and now I am getting selection menu in startup
    and i am able to start Linux and window 8 in same computer 🙂

    and for your information : windows 8 is awesome for laptops ..its cool nice and great interface.. performance is not slow as i aspect.
    and you can buy window 8 in just 1,999 INR
