My ASUS notebook K53E is currently running under Windows 7. I would like to install Ubuntu 12.04 alongside Windows and be able to choose between these two systems each time I start the computer.
I have downloaded Ubuntu and burned a DVD. When restarting my computer (with this DVD in the drive) the DVD is ignored, i.e. Windows is run as usual. When I press delete while rebooting (still with this DVD in the drive) a BIOS set up menu is shown with plenty of things to enable/unable, add, etc. But I don't really know what to do/choose.
When I exit this menu, again, the DVD is ignored, i.e. Windows is run as usual. Bascially: I'm stuck.
Question: Is it worth while trying to install Ubuntu from a USB stick rather from a DVD? I.e. is Ubuntu easier to install from a USB than from a DVD? Or am I likely to run into the same kind of problems?
Thanks Alina and DVJ for your answers. So I guess the answer to my main question is: no, installation form a USB stick is not really easier than from DVD.
Following your advice about the boot priorities, I have now achieved a little improvement: I now get to GNU GRUB where I can choose to 'install Ubuntu'. Unfortunately, after that the screen goes completely grey and nothing happens.
