I searched the forums, looking for similar issues, but haven't found what I needed.
So here's the background info:
I bought my mum a new Lenovo G500 laptop that came with only FreeDos on it. I've been trying for 2 days now to install Ubuntu. I tried by burning ISO to a DVD, but it didn't work and I since I ran out of DVDs, I turned to a USB stick.
I downloaded iso from Ubuntu official page ( I tried to download ISO via Unetbootin, too) and burned it to the usb using Unetbootin, but I was getting either 'isolinux.bin Invalid or missing' or 'Invalid or Corrupt Kernel Image' message for the first 5-6 times I tried. I tried different ISO-to-USB burners, different Ubuntu versions, different formatting options...
I finally download ISO for 12.04 through Torrents and it worked, BUT after the installation, I got a message telling me it didn't manage to read/open apt package, something like that, because the package is not authentic.
So I downloaded another one from Torrents, but it wasn't good as when I started the installation process, the graphics looked 'broken'. 2 times I got a black screen after the BIOS screen.
I really don't understand it, why is Ubuntu so hard to install?! Even when the package files come from their own official website?
If anyone can help me and spare me this misery, please advise!
