Failure to Boot Windows 7 after Ubuntu install

I recently installed Ubuntu on my PC dual-booted with Windows 7. After rebooting it went through the usual startup screens, but the OS selection screen never shows up. I cannot get either system to boot.

I have formatted the partition holding the Ubuntu to no avail and I really don't want to get rid of Windows.

I am currently stuck using the Live session disk to boot. Any help is greatly appreciated.

To get back into Windows, you’ll need to reinstall your Windows boot loader. I suggest this tutorial http://www.howtogeek.com/howto/33433/restore-the-windows-boot-loader-after-an-ubuntu-update/
