I was going to put more info here, but I think it's important to go a step at a time and oldfred is the leader here. Indeed the command is a Linux command, not a Windows command. What I would recommend is booting the LiveDVD and select "Try Ubuntu" to be sure that boots and you get to the desktop. If so, then from there you can open a terminal window (ctrl/alt/F1) and put in the command oldfred gave you. If you have internet access while on the LiveDVD, then copy and paste the output back here. If you don't have internet access then I would just copy the output to a removable media (like a USB flash drive) then reboot Windows and copy the output back here. Oldfredd can use that information to help you further.
