It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
As I understand, you're not able to boot your Windows OS and it only boots into Ubuntu. I suppose that Grub2 wasn't installed within your Ubuntu 11.10 installation To install and load the grub items, just write these in your terminal.

Use Following Commands
After the boot command you will go into grub 2 menu. Select to boot up ubuntu, and run this command to restore grub.
