I have an old Windows laptop on which I've installed Ubuntu. At least, that's what I thought.
I created a USB Boot disk by following this online guide and completely whipped out my hard drive to install Ubuntu on it. All goes according to plan, except when I try to boot my laptop.
I only get the message "Operating System not found". But when I boot from my USB flash again, I get the warning Ubuntu 12.0.4 is already installed and will be overwritten.
I've run the Boot-Repair and came up with this result.
I'm fairly new to Linux, so I'm not entirely sure what it al means... How can I boot my Ubuntu installation on this machine?
