Finally reinstalled grub First i used my ubuntu live cd and in a console ran $ sudo grub This puts you into a grub shell. grub> find /boot/grub/stage1 This will return a value which looks like (hd?, ?) this is where you will find /boot/grub. '?' will point to the specific partition of your disc which contains the boot grub for example (hd0,1) grub> root (hd?,?) Use the value from the find command eg (hd0,1) Finally the command which will install GRUB into the MBR. ...
