Ubuntu – When to remove the pendrive after installing Ubuntu

I have had almost the same problem when installing Ubuntu 11.10 on my laptop. For some reason I do not get the usual installation graphical interface, however I get to install Ubuntu. But after installation is complete, I reboot the machine remove the pendrive and Ubuntu starts loading but then it stops, a cursor appears on the upper left corner of the screen and nothing else happens... ever again!!.

I thought it may be an issue of the pendrive, since the installation interface was not as expected for 11.10, so I burn a Live CD and rebooted from it. So far the installation process has no problems and its graphical interface is working fine. I will report back after installation is completed. So far it seems that the problem was the USB installer being faulty.

Running these commands should fix your problem:

sudo apt-get update
sudo apt-get --purge reinstall oracle-java7-installer
sudo apt-get upgrade

If they do not, then please edit your question to include all the text from the Terminal from when you ran them (as the output would still be diagnostically useful).
