You may need to reinstall grub when windows is installed after ubuntu (or if you reinstalled windows in dual boot (Windows and ubuntu) system). I used following steps for reinstalling grub in order to login to my Ubuntu 10.04 after reinstalling Windows 7 on my machine.
1. boot the ubuntu LiveCD
2. Open a terminal and type
sudo fdisk -l
This list the partition tables, and in my case root (/) partition is on /dev/sda9.
3. Mount that partition using following command.
sudo mount /dev/sda9 /mnt4. Run the grub-install command as below. This will reinstall the grub 2
sudo grub-install --root-directory=/mnt /dev/sdaHere "sda" is the hard disk on which your Linux distribution is installed!5. Reboot
6. Finally Refresh the grub 2 menu using following command
sudo update-grubNow everything should be fine :)

Worked like a charm for me too on xubuntu 11.10-amd64 + Win7-x64. Thanks alot for sharing this.
Thanks very much, I spend 3 hours without your help, but by your help, it was only 5 minute.. very great..
Thank you! This was perfect
Worked very good, now got back my BackTrack 5 and Win7 64bit OS running too :)
Tnx !
Much Appreciated!
Just wanted to say: Thank you very much :) works like a charm
Worked perfectly for my lady's laptop after she wanted Windows 7 installed next to an existing Xubuntu installation. Interestingly, both the official Ubuntu-provided solutions, Boot-Repair and a terminal walk through, did not work at all. Perhaps consider sending this upstream so it makes it into the Ubuntu documentation?
Thanks again! Made me look like a genius. :)
