All, I just sold my June 2010 Mac Mini on eBay and want to format it back to factory settings and install Mavericks on it before I ship it off. I have Windows 7 partitioned on it as well and want to remove that before it's gone. Right now I cannot access the DVD drive since there is an error that does not allow the drive to open and accept discs. I read about going into the partition settings and resetting it from there, but will that 1) erase Windows 7 from the machine and 2) allow me to go and reinstall Mavericks on the thing? Thanks for your help.
