Hi, I just tried to install ubuntu onto my laptop by installing onto an SD card. The installation seems to run successfully and then prompts me to reboot. However once I do so I get nothing but a grub rescue prompt, the sd card is still in. This now means I can't access the ubuntu I just installed and I also can't access the windows partition. As you can imagine I'm a little worried :P.
Please bear in mind I'm new to this and may come across as a bit dim!
I tried running a script I found on another forum here (link to script here: http://sourceforge.net/projects/bootinfoscript/)
and got this result:
