I am new with Ubuntu it seems to me like a great option to get over Windows. I have never used it though so I am completely lost. I had Windows 7 64 bit installed on my desktop, (It has a AMD Phoenom II X4 945, ASUS M4A89GTD PRO (No USB 3.0), 4 gb ram DDR3, 500 HDD). A disk with Ubuntu 12.something was given to me to install it and I did but then I was told to upgrade to 14.04 the latest version and the system did not recognize my password. Then we tried with a disc 14.01 but it just do not work. Then I put a new hdd in but now even though when it accepts the hdd I have the following error:
"Reboot and select proper Boot device or insert Boot Media in selected Boot device and press a key"
Then if a press a key I have the same error again. The boot order that I have is: CD HDD USB
I hope you can help me folks, Thank you
