I am in the same boat, i was trying to install linuxMCE 810 so i downloaded the DVD.iso and then realized i didnt have a working DVD drive, so then i tried mounting the iso to a flashdrive using unetbootin and booting from that, it got to the kbuntu load screen then the screen just started flashing with lines on it and didnt go any further. So now i installed kubuntu, but neither of the download links on the download page of linuxmec.org work, so for right now i cant install to do some testing
