Lost your grub after windows installation.. How to update, reinstall the grub in (BOSS) Linux?

Scenario:
  Once windows(vista, 7, xp) installed after the linux installation then one will lost his grub and there is no way to select the OS during the system startup(Dual Boot).  By default windows installs its boot loader into the MBR and not care about the other OS in the same machine.
So how to get the old grub with the new Windows OS entry in it..? here follows the steps..

1. Insert your BOSS Linux DVD(live, install, utility all are in the same DVD) in the drive and reboot your
system.
2. Select the live option and boot your system in live mode.
3. Click and mount the Linux partition whose grub is going to be used.
4. Now copy the mount location in the addressbar(location: it is somewhat like /media/some_chars_numbers)
5. Open your "root terminal" Applications --@ Accessories --@ Root terminal and issue the following commands
6. #mount --bind /dev /media/some_chars_numbers/dev
7. #chroot /media/some_chars_numbers
8. #update-grub
This updates the grub with the newly installed Windows OS entry in it
9. #grub-install /dev/sda
This installs the grub in the MBR(Master Boot Record).

Thats all.. now reboot the system and remove the DVD.  Now system will loads with the new updated grub where you can see all the OS available in your system and you can select(dual/multi boot) the OS which you want to login.  That's all :)

No display and Input signal out of range error in Linux?

Some times after the installation of linux(Debian based) one will end-up with the terminal and no GUI.  So, how can we fix it? Some quick checks 

1. Restart the gdm service by following command

$sudo /etc/init.d/gdm restart

2. Start the x-server

$sudo startx

3. Even after this if you are not getting the GUI and or got the error message like "Input signal out or range" then you need to edit your xorg.conf file.  This file is at /etc/X11/xorg.conf

i  ) Open the /etc/X11/xorg.conf file in your favorite editor with root privilege

ii ) Go to the section "Screen"  -> "Display" -> "Modes" put only the value "1024x768" and remove the all other values.  (If you know the correct resolution of your monitor the adding it is not a problem.)

iii) save the changes then again start the x-server(as like in quick check 2)

Hope this will help you.
