I used WuBi to install Ubuntu. I did this after I did a factory restore on my Windows 7 Desktop, and cleaned out unnecessary junk, defragged, etc. I also did some hardware tests, and everything seems to work. This is my first experience with Ubuntu or any Linux system.
It shows the grub screen where it's asks if I want windows or ubuntu, and I select Ubuntu. Then Ubuntu crashes at the login screen(or just prior to it), makes repeated beeping noises(in a loop), and has these strange diagonal lines through the screen.
Any suggestions on how to fix the problem?
