Dual-boot: Can't select Windows at boot

view story

http://askubuntu.com – I have a computer with 2 operating systems dual booted: One is Windows 7 and the other is Ubuntu. My Ubuntu installation is installed within the Windows partition via wubi.exe. I'm not using grubby, but windows 7's default bootloader. From within the windows settings i have set the time to choose the operating system to boot to zero, and as Ubuntu is at the top of the list, it boots automatically, not giving an option to load my windows 7 installation. My problem is that I can not access my Windows 7 Operating System. It is essential to my work, so I am unable to remove this partition. Cou (HowTos)
