Steps to reproduce This result was consistent after five different installs.
Outcome I'm having the same issue, after install I shut down remove the usb it will boot the first time to login screen no problem, after a second shut down or restart it hangs at the spinning arrow. Expected Outcome Smooth start up with boot splash to login screen. Workaround Tap the F8 key before boot splash appears, continue to tap F8 when scrolling text appears, it then continues to login screen. Temporary Fix Remove "quiet splash" from /etc/default/grub - GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" Result Scrolling text on startup, however a very quick boot to login screen, no hanging.
