I have two hard drives with Windows 7 on sda and Ubuntu 13.04 and Ubuntu 12.10 on sdb. When selecting 13.04, I get a cursor that flashes, then a message with my computer info and tty, then a login request. I ignore that and 13.04 will boot after about 20 seconds. How do I get rid of that. My plan is to wipe out 12.10 when Mint 15 comes out. I suspect I need to do something different during installation as I keep getting the same error message every time a new version comes out. Thanks for any help.
