Q--"I want to remove fedora 10 and install ubuntu 9.04-desktop-i386
I have that Ubuntu CD
I booted into "try ubuntu without effecting your system""
You should boot the ubuntu installer into "install mode" not the "try" mode. In your case the try mode simply desisted from installing. You should choose the install ubuntu mode.
One thing: My suggestion is to reformat your 2nd partition first (where fedora resides) into an ext2 or ext3 before installing ubuntu in order to avoid unexpected conflicts. Use the ubuntu installer, it should offer you reformatting choices somewhere in stage 4 or 5.
Another thing: First check the md5sum of your installer cd if you'd get the correct sum, this to ensure that your cd is healthy. Download the md5sum offered from the site where you got it, then use the terminal to inquire the iso file.
Hope this helps.
