yes, i can see wubi* files in C: drive.:woohoo:
are you sure that it is now safe to delete these files and edit the bootloader?
is it safe to delete the partition having ubuntu?
i m just waiting for your yes so that i can confidentally do that.:)
Those files are the boot instructions, kernel image and the virtual disk(s) that hold your ubuntu installation. In the wubi installation the files are not written to a new partition, but are written to the virtual disk file(s) that are stored on your C: drive.
Now if the ubuntu physical partition was used then you may have installed two occurances through seperate install attempts, one as a physical install and the other as a wubi installation. Buy removing the files and the partition then you would be removing both installations of ubuntu and all data that resides within those installation.
You can safely remove all of the wubi and ubuntu files and remove the ubuntu boot entry. But by removing these files the ubuntu boot entry will not work and you will loose all access to your previous ubuntu installation.
Feel free to report back and ask questions when you are willing to allocate some time to fully installing and distro. Who knows, we may help you find some functions that will make you question ever going back to windows ;)
