The menu you are referring to is the windows boot menu. Wubi adds an entry in there, and it's for the wubi install. So, if you uninstall wubi, you won't get that menu anymore (* sometimes the uninstall fails to remove this and you have to do it manually). It will not work at all if the wubi install is fubared.
So, first off if you haven't already done this, confirm you can boot the 10.04 version make sure it's working fine. Then boot windows 7 and see if it's happy - windows doesn't like you splitting it's partition, but it might run a chkdsk and then be happy.
Then if it all works, customize the grub menu as per the link I gave previously and uninstall wubi, making sure it removes that second boot menu. Then you should be sorted.
If unsure of anything, post the results of bootinfoscript (http://bootinfoscript.sourceforge.net/) so I have a better idea of what's going on.
