At https://launchpad.net/ubuntu/+bug/58358/comments/13 Ben said this bug was fixed and uploaded to dapper-proposed and edgy-proposed. Presumably it will be fixed for feisty. Even if it doesn't make its way out of the proposed repos, you can do a hd-install as said for edgy at http://ubuntuforums.org/showthread.php?t=316093
Make sure you get the initrd.gz and vmlinuz images for feisty from http://archive.ubuntu.com/ubuntu/dists/feisty/main/installer-i386/current/images/hd-media/ The edgy files may not work for feisty. -- CD detection failed on install. https://launchpad.net/bugs/55232 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
