Introduction

A (re)installation of Windows will overwrite the Grub bootloader.

This is a manual to restore Grub without a new installation of Pardus.

What do we need ?

• We need the Pardus Live or Installation CD or USB version.

If you haven't any Pardus CD. Check: http://www.pardus.org.tr/eng/products/index.html

• Configure your bios settings for booting from CD or USB.

Enter The Grub Menu

With Pardus 2007.x CD

• Reboot from CD and wait untill the language screen is shown.

• Push the arrow-down key to stop the timer.

• Push the c key and the grub screen will appear.

• Continue with "Installing Grub"

With Pardus 2008.x/2009 CD and USB version

• Boot "Pardus 2008/2009" with F2=English (US) language selected. (this is to have the proper keyboard layout)
• When the "Welcome !!" (license) screen is shown press Ctrl+Alt+F1 (simultaneously).
• A console screen will appear with "pardus ~ #" as the last line.
• Enter grub in the console, then press <enter> and the grub screen (with "grub>" as the last line) will appear.

Installing Grub

• Type root ( and then press the Tab key. ( there is a blank between root and ( ). This will list your possible disks (hd0 hd1).

  When there is only one disk installed the filling up of 'root ( +Tab' will be 'root (hd0,' 
  and no disk selection is necessary (in this case skip the next step).

• Press again the Tab key and the partitions from hd0/hd1 will be listed.

  Check for the Pardus partition number by looking for disk format ext3 or ext2fs. 
  In this example I presume partition number 4 is the Pardus partition. Change the number when necessary.

• Write root (hd0,4) and press <enter>. ( 4 is the Pardus partition as mentioned in the previous item )
• Write setup (hd0) and press <enter>. (hd0 is the first hard disk from which the bios will boot)

  When we get 'Error 15: File not found" it is not the correct partition and we can start at 'Type root (' again, 
  and when we get "...... succeeded. Done." Grub has been restored in MBR of hd0.

• Press Ctrl+Alt+Del to restart your computer.
• And the Grub Menu will appear.

FIXMBR

Press Enter. Answer all the question as y ( yes ). You're done. Just restart your pc.
