    I have no advice yet, but I am facing exactly the same problem. Will post back if I find the answer.

    I think you have to delete the Macintosh HD first before it accepts it to install there by opening disk utility from the instalation menu

    Nothing. Start from scratch. OS X does not support other boot loaders, but other boot loaders support OS X (and Windows, Linux, ...).

    Fixed

    OK, I fixed it. What you need to do is to make sure you have a functioning Recovery Partition under Lion before you try the upgrade to Mountain Lion. Following these instructions worked for me. I didn't lose anything - not even my Ubuntu partition. Enjoying the Mountain Lion goodness!
