  Grub bootloader is an open source boot loader. It facilitates switching between two OS without similar kernel or same kernel. Lets say two operating system. When you install windows, you don't need GRUB. Linux preferably is used with GRUB since your other OS, Windows has a different kernel. And naturally, if it was not installed properly in the first place, It will hamper switching between different operating system. So you reinstall it and as you say, it is working fine now.

  Ok thanks, but what may the reason behind ubuntu working properly with windows 8, this problem faced by me only in windows 7 each time.

  windows 8 's bootloader is enhanced version unlike the one which was in windows 7. Windows 7 bootloader did not support cross kernel OS. Whereas in windows 8, that feature is added. You can easily load any operating system alongside windows 8 using its default bootloader.

  I also got this problem with dual boot.
  You need to login into windows 7 and use EasyBCD and manually add linux boot.

  This should solve your problem.

  Thanks ianoop, but I had this utility, but I wanted some other solution and get to know what's the problem behind this.
