I use win7 + ubuntu 14.04.

I'm not sure how to cause this problem.

The situation is I can see boot menu with win7 but without working.

When I press enter on win7, it splash and show the same menu again to let me choose.

What's this situation?

How to fixed it?

Thank you~

first try this:

  • insert your windows 7 instalation cd/dvd and boot from. choose your language and hit next. when prompted to "install now" appear just look left down to that windos and press repair your computer.
  • wait and a new windows rise with operatings system instaled in your pc. click on "windows 7" and hit next.
  • in the next window press "Command "Prompt". when command prompt window appear type that:

    bootrec /fixboot
    

    press enter and:

    bootrec /fixmbr
    
  • press enter again and then close that command prompt window and restart your pc. Note: between "bootrec" and "/" there is a space, dont forget.

  • After that i think you will no longer have option to choose between operating systems to boot on startup. you will must to repair grub.( i think you can do that with ubuntu live cd. but i am not sure. Good luck. Let me know if you fix that. (Easy way is after repair windows 7 boot format the linux partition and reinstall linux:D)

To repair grub after fix windows 7 boot:

Try this.. To recover grub: 1.Open the live version.

2.Open the terminal and run sudo fdisk -l to see where Linux is installed.

3.Run: sudo mount /dev/sdaX /mnt where X is the number you have found Linux word in

4.Run: sudo grub-install --root-directory=/mnt /dev/sda

to install grub.

5.Run: sudo update-grub to update grub, and if this command didn't work run it after rebooting.

6.Reboot.

Note:

For me #5 command didn't work. So i restart the computer and after restart, computer boot directly in to ubuntu O.S. So i loged as root and write this command:

sudo update-grub

That solve the problem. EugenB
