Hello, there, Ubuntu forum posters. Last night, I created a Linux-ready partition on one of my external hard drives. I then booted up my Ubuntu installation DVD, loaded the installer, and started to install the system. The installer automatically noticed that my external drive had a partition fit for Ubuntu, and successfully installed there. Now, I am clueless as to how the newly-installed OS can be booted from this drive. Logically, I tried booting my computer whilst holding the alt/option key, but that only gives me two options: my main drive, and a drive entitled "Windows." Thinking that the second drive might actually be my Ubuntu drive, I chose that one. Upon selecting this drive, a grub error screen appears.
Is there something here that isn't being done correctly? Is there a special command I can input to resolve the grub error? This Linux nub here has nary an idea as to how his problems can be fixed.
