This is actually my first time trying out Linux. And I just installed Ubuntu 16.04 on a used PC I just bought, HP Compaq 8300 Elite SFF with two hard drives. After buying it, the first thing I did is performe a clean install of Windows 7 Ultimate on my first hard drive. Thereafter I created two partitions on my second hard drive. One for installing Ubuntu and the other for storage purposes.
While installing Ubuntu I created partitions for root, home and swap. Then I mistakenly chose my second hard drive to boot from resulting in starting Windows everytime I turn on my PC without showing the boot menu. With the comments and answers from CelticWarrior, Zanna, hunch and duncan Ubuntu is now booted from the first hard drive so that the boot menu shows when I turn on my PC giving me the option to choose between various ways of running Ubuntu and starting Windows.
I already tested starting Windows and everything seems to work fine. However, when I want to start Ubuntu, I can't get past a message showing:
'Welcome to emergency mode! After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to try again to boot into default mode. Press Enter for maintenance (or press Control-D to continue): _ '
That's all I see and no matter what I try I can't seem to continue.
I'm a total newbie concerning Linux and I still need to start my first session with Ubuntu. And I hope I can get some help on this great website.
Thank you in advance!
Sincerely,
