I recently purchased a HP Pavilion with Windows 8 pre installed. I purchased a second hard drive and want to run Ubuntu 12.10. Is it possible to boot from second hard drive and run Ubuntu without even touching Windows 8, or having to disconnect the first hard drive every time I want to run Ubuntu? I'm new at this and could use help. I have looked at many forums and all only discuss installing Ubuntu on the same hard drive as Windows 8. I want to dual boot with two separate hard drives. Any help would be greatly appreciated.
