If you have used Windows support then I would assume you have used the recdisc command, but if you haven't, boot up into the Advamced Boot options (usually by tapping F8 as you switch on) and select Safe Mode with Command Prompt.
I normally use a DVD-R rather than a RW disc but if RWs have worked okay for you then continue.
Insert the disc then at the prompt enter recdisc
This should correctly identify the CD/DVD drive then follow the prompts.
Remove the disk when completed and to exit the Safe Mode enter shutdown or shutdown /r
The latter will reboot the machine back into normal mode.
If you still get any errors then I think it would be a factory reset, but Shane may have another workaround.
