I've been running Ubuntu 10.10 Netbook Remix for many years and didn't really understand that I had to update it to keep it running well. Now everything is extremely out of date and I'm having a hard time running anything on my computer anymore. I tried doing updates (via update manager and
sudo apt-get update)
as well as doing an upgrade, many many times (consulting Ubuntu forums constantly) and for many reasons they never worked.
So I thought I would start over and just install from scratch from a live USB. I created the USB properly with Ubuntu 12.04, but my computer (currently running 10.10) won't boot from the disk. It works on other computers - which is how I know I did it properly.
I'm a Ubuntu novice, what can I do?
