I am an Ubuntu newbie that's trying to install Mate (not Mint) on a 6 or 7 year old Dell laptop. It appeared to install correctly but when I restart it doesn't boot. It just displays something to the effect of "No Partition available". I do not have any other OS installed. After some searching I learn about Boot-Repair. I run it and get the an error message from that too.
Some more searching just brings up something called UEFI. But I am unsure how or if that is relevant to my version of this problem.
I know you veterans are probably sick of seeing every third Ubuntu convert ask this same problem. But if you could point me towards a solution then I can finally leave windows behind.
