I have a laptop without an internal hard drive and I'm struggling to make it work from a USB drive.
I have used Universal-USB-Installer-18.104.22.168 to install Ubuntu onto my USB drive. I specified a 250 MB persistent file. The system boots and it all works fine, but I can't really save any changes or even access the USB drive, can't create folders or copy files to it, and can't connect to the Internet. When I try to access the Internet, and enter the password of the access point, it tries to connect and than says "network disconnected" and asks for the password again. I know the password I am inputting is correct. (It also fails to save the password.) If i restart it, all my changes like the desktop wallpaper and the wifi configuration are gone.
I figured I need to use the install shortcut and install it permanently onto the usb drive, but when i try to do that, I choose my language and get stuck at the second screen with check boxes and stuff. On this screen, the continue button doesn't work--I can't press it.
I figured it doesn't want to install onto the same drive so I tried to install it from one USB drive to another. I still couldn't get past the second screen for the same reason. I tried to use all the disk management utilities and format the second drive but nothing i did had any effect.
