I'm new to Ubuntu so bear with me. I have a Windows 7 computer and I recently used the Windows installer to install Ubuntu 12.04 (followed these steps: http://www.ubuntu.com/download/desktop/install-ubuntu-with-windows).
Upon installation completion, I restarted my computer. When it booted up, it automatically booted into Ubuntu, rather than giving me the Windows Boot Manager to be able to chose between Windows 7 or Ubuntu (which is what I want). So I shutdown my computer and turned it back on, this time pressing the space bar to load Windows Boot Manager. It gave me the option to boot into Windows 7 or Ubuntu. So far so good.
However, when I select Ubuntu, rather than booting up the Ubuntu desktop, it takes me to a black-screen grub command line. The command window displays the following:
GNU GRUB version 1.99-21ubuntu3.10 Minimal BASH-like editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completion. grub>_
I try using the "boot" command, but that gives me the following error: "error: no loaded kernel"
Any ideas what went wrong or how to fix this? All I want is to be able to choose between booting into the Ubuntu desktop or the Windows 7 desktop.
