Ubuntu 11.04 installation problems

I just downloaded ubuntu 11.04 using the wubi installer. However when the download completes it asks for a reboot to finish the installation. Boot manager should appear giving me the option to choose either my current OS which is XP or ubuntu but boot manager does not pop up?

The only options it shows is ""windows xp home edition" - "do not select this/debug" - "microsoft windows recovery console"

The above bold text is all that pops up on screen and there is no option for ubuntu. When I go into windows I can see that the ubuntu iso is on my system and also it has created its own 30GB partition but again no matter how many times I reboot my system boot manager is no where to be seen.

Anybody have any advice on what I should do? Do I have to enable boot manager and if so how is that done?

you need to not reboot but shut down the computer then see if you get a boot menu.
