you need to edit the grub and delete the partition in case you have a separate partition for the old install.

1-make (or find where you stored it) a Ubuntu CD
2-boot on Ubuntu 11.10
3- Ctrl+T to open terminal
4-terminal: sudo apt-get install gparted
5--terminal: gksudo gparted
6-remove 11.04 partition via gparted
7-terminal: sudo update-grub
8-terminal: sudo reboot

If reboot fails, reinstall Grub2: https://help.ubuntu.com/community/Grub2#Reinstalling_GRUB2 (I prefer chroot method)
