I just installed Ubuntu 11.04 on my computer, that was already running Windows7 perfectly fine.

  • Windows is on /dev/sda3 and Ubuntu on /dev/sda6 - same HDD, but different partitions.

The problem is right now when i boot it goes into grub and i can choose:

  1. ubuntu
  2. memtest86
  3. windows7

but when i click Windows7 it return to grub again. Please help me, i really need this working.

Have you tried running "sudo update-grub" in a terminal when logged in to Ubuntu? After running that, try again and see if there is any difference. –  zookalicious Apr 29 '11 at 21:39

did you remove the loader for windows as i saw in many pre-configured windows 7 machines that it comes with partition for its boot loader and when you chose windows 7 from grub menu it will trigger the boot loader of windows. so the question is did you remove a small partition less than 100 MB which holds the windows loader or maybe there is something happened to it. if so then you got problem with windows and i quess this is the issue you can install the MBR for windows by using ubuntu live cd look here: http://blogs.deepal.org/2009/06/how-to-fix-mbr-using-ubuntu-live-cd.html

but this i think will replace the grub and you will boot to windows directly so you will not be able to see the ubuntu and then you need to follow another solution to bring ubuntu back by following this: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows
