X being the partition number

This i had seen in some other forum , can you just replace the --root directory and write exactly what should be given there ? It will help newbie to understand better

So if I have windows installed on my first partition, and then for my extended partition, the partitions, /boot, /, etc., do I want to install it to the first one (NTFS) or to one of the linux partitions? I read that the mbr is located at position 0, so I wasn't sure if I install it on the windows partition, but I was afraid it would write over windows.

Here is explained for Ubuntu OP hasn't mentioned what OS he is using ------> https://help.ubuntu.com/community/Gr...talling_GRUB_2

forget this part

Boot from live CD or USB then open a terminal and type

Code:
sudo fdisk -l
Note: -l is lowcap L, no the number 1

You'll see a list of your drives and partitions, (like /dev/sda1. Make note of the partition you have your root for Linux)Here we will assume sda1 is the partition you have installed Linux
then do
Code:
sudo mkdir /mnt
Code:
sudo mount /dev/sda1 /mnt
Next do
Code:
sudo chroot /mnt

so you did not fallow the advice on almost every guide on dual booting
1) install windows
2) install linux
( grub will boot windows, windows will NOT boot linux )

you made a /boot partition
install grub there

then in the bios set THAT partition to boot first !
or using Gparted live cd
put the "boot flag" on that partition

Finally solved... did a complete re-install, but that did not work (of Linux). Then I followed this tutorial. I was mounting the sda# instead of just the sda partition.

Same here, did a complete reinstall ( including Windows) it worked fine, unable to find what went wrong initially.
