I tried to install Ubuntu Server from a flash drive using UNetbootin, because my optical disc drive is broken. When I created the bootable drive using UNetbootin, there was no problem.
When I tried to install it on my computer, after booting it shows the UNetbootin menu where you can install Ubuntu Server. But when I choose to install it, my computer restarts and I land at the UNetbootin menu again. This process repeats.
Is there something wrong with my computer? Is the drive broken or is that a software error?
How can I install Ubuntu Server from the flash drive, then?
