I've tried so many combinations - all I want is a fast Ubuntu Live USB disk with persistence that works. What I've tried so far:
- Using unetbootin on my Mac, choosing some "Space used to preserve files across reboots (Ubuntu only)".
- Result: Doesn't boot at all.
- Using unetbootin on my Mac, choosing no such space.
- Result: Boots fine and very fast (doesn't even show the annoying dialog "Try ubuntu/install ubuntu" at startup!), but has no persistence. (So I have to choose my keyboard layout, install programs I need, etc. every time)
- Using Startup Disk Creator from my Ubuntu 11.04 installation.
Using Startup Disk Creator from my Kubuntu 10.10 installation, gnome version (usb-creator-gtk).
- 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, kde version (usb-creator-kde).
- Result: Actually works: Reserved space can be selected, installation works. But after booting, I get the screen "Try ubuntu/install ubuntu". Clicking on "Try ubuntu" takes me to the desktop - but only after waiting 5 minutes (every time!). It also doesn't seem to keep my keyboard settings.
I know, that instead of creating a startup disk, I could install a full ubuntu system on the USB stick. But as far as I know, this isn't very good, because /tmp and similar directories will then also be on the USB disk, which is a) slow, and b) not very good for the USB disk due to frequent overwriting.
I'm frustrated. So has anybody managed to create a working Ubuntu 11.04 Live USB disk with persistence?
