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.

Thanks,
Todd
