My intention was to build a dual boot XP Pro 64 and Ubuntu media server. I had installed the AMD64 version of Ubuntu 8.10 server and thought that I would be able to install Apache server. I need a GUI to work in. I tried to boot and install Mythbuntu 32 bit 8.10, but my machine now won't recognize the CD media of the iso of Mythbuntu or the originally installed AMD64 version of Ubuntu server. When I boot in XP 64, I can see the CD and I have the boot sequence to start with CD then HDD. Any suggestions? Had installed XP first then during the Ubuntu install had split the hard disc into two additional partitions, first for the Ubuntu install and second one for a scratch disc. Used the default disc format for the two additional partitions. Think that this is a problem with the download of both mythbuntu 8.10 and ubuntu 8.10. Is there a way to verify the Iso file is intact. Both discs would not start a boot process in another windows machine.
