When you get dropped into the minimal (initramfs) prompt it gives you some good suggestions. For example. You can do "ls /dev" and "cat /proc/modules" and you can probably even try to run a mount command maybe. You can also double-check things like "cat /proc/cmdline", etc. See if you can determine what devices in /dev are actually available, such as your sda, hda, or xvda devices. Hope that helps.
