I've been a user of version 12.04 for about 6 months with a dual boot system with Windows. In an attempt to delete Windows, I made a mistake and needed to reformat the Hard Drive. I had version 12.04 on a CD and tried to do a boot install. It didn't work, probably because I needed the correct installer. I found an old thumb drive with Ubuntu installed, and was able to load version 10.10, thinking that the update process would be easy. Unfortunately, it wouldn't update because the support for that version ended last year. So I downloaded the current version 12.04.4 to both a DVD and to a thumb drive, but neither would install. I tried to work with the terminal function, but have not been able to figure out the correct syntax. Help. Should I reformat the drive, if so, How? Or is there another way to install version 12.04 that I haven't tried?
