It also doesn't seem to keep my keyboard settings. Clicking on "Try ubuntu" takes me to the desktop - but only after waiting 5 minutes (every time!). But after booting, I get the screen "Try ubuntu/install ubuntu".
Result: Actually works: Reserved space can be selected, installation works. Using Startup Disk Creator from my Kubuntu 10.10 installation, kde version (usb-creator-kde). Result: I can select the "reserved extra space" option, but installation doesn't work (fails when installing the bootloader). Using Startup Disk Creator from my Kubuntu 10.10 installation, gnome version (usb-creator-gtk).
But it doesn't work with Ubuntu 11.04 anymore (see also comment #14). I know I know, there was bug 557775, and many people say that the workaround from comment #4 works for them.
Result: I cannot choose "reserved extra space" at all. Using Startup Disk Creator from my Ubuntu 11.04 installation.
(So I have to choose my keyboard layout, install programs I need, etc.
Result: Boots fine and very fast (doesn't even show the annoying dialog "Try ubuntu/install ubuntu" at startup!), but has no persistence. Using unetbootin on my Mac, choosing no such space. Using unetbootin on my Mac, choosing some "Space used to preserve files across reboots (Ubuntu only)". I've tried so many combinations - all I want is a fast Ubuntu Live USB disk with persistence that works.
