I am new to Ubuntu. I just installed 12.04 LTS onto a second hard drive in my Windows 7 machine. Now when I start Ubuntu it sits there flickering between a whole ream of console output and a screen with the single word "Ubuntu”. The console output seems to be the same screenful of information continuously repeated. The flickering is almost fast enough to make the two displays appear to merge into one.
It will keep doing this until I hit random keys on the keyboard (the arrow keys); once I let it go about 10 minutes and it still got nowhere until I hit some keys; after that it took a couple of minutes to finally reach the login screen.
I had briefly trialled Ubuntu on another Windows 7 machine and had a completely different experience than this one. Most notably, instead of GRUB asking me which OS to load (on the other machine), I am seeing what appears to be the standard Windows boot selection.
The only differences between the two installations (other than a couple of month's passing of time) is that the first one was a 32-bit machine installed via USB whereas this one is 64-bit and I installed from a DVD.
It is not at all how I expected my experiment with Ubuntu to go. Does anyone have any suggestions for how I can make it start properly?
