I have a Lenovo ideapad g580 with Windows 8 from the box.

When I insert a USB stick with Ubuntu 12.10 64-bit, it is just giving me to try it, not to run it from the USB.

When I put it on my other laptop it is just running and I can save data and files, and when I shutdown the laptop the data aren't deleted.

And on the Lenovo when I work on Ubuntu, all the data after restarting the system are deleted.

it is just giving me to try it, not to run it from the USB Is not the same thing? Also, where the data is saved in the other computer? If you want to install Ubuntu in the USB flash drive review this post: How do I install Ubuntu to a USB key? – Lucio Mar 11 '13 at 23:06

I am also on a Windows 8 Lenovo ideapad (Z580). I don't know what is going wrong with yours, but I think you might be able to help me... Does your Windows 8 still work after you unplug the USB stick? I want to use ubuntu but if it breaks my Windows 8 then I had better not... Sorry I can't be more useful in answering your question... How did you get Ubuntu onto the USB - I know you probably already know this, but try using PenDriveLinux and persistence mode. I haven't tried it but it's supposed to make the USB remember each session like on a normal pc.
