I tried to install Ubuntu 11.04 side-by-side with my Windows on my HP Pavillion g6, but it caused me a lot of different troubles.
So I tried to reinstall Ubuntu on all of the disk memory with a live-boot cd, but everytime I use the cd it takes me to a login-screen for Ubuntu (with no users to choose) and wants me to write in a username and a password. From here I get nowhere and now I'm stuck. Should I try to install Ubuntu some other way or does anyone have an idea of what I should do? Thanks for your help!
Update for answer by Pavlos G:
My problems are many. First of I left the idea of having Windows side to side with Ubuntu and wanted to install only Ubuntu. So Windows is not really the issue, but the problems I had (or have) were two major ones:
First, Windows would not start. It only said "put in your Windows installation cd" and I think that something went wrong during the partitioning part of the installation.
Second first did not won't to start at all which I learned how to fix, but than I got other problems. The computer asked me to install a special device for my graphic card (AMD Radeon HD 6470M) and I did. When I reboot the computer later on Unity was gone and Ubuntu had gone back to Gnome. So I figured out because I had nothing on the computer (it's new) I could make a reinstallation instead. Which no is the problem, but I think your link maybe can fix it. Thanks!
