I have been having trouble installing Mythbuntu 12.04.2 64bit. I have downloaded the image and burnt it to CD, however my computer does not proceed with booting the CD, like it does not see it as bootable. Much like the problem presented with this post "Unable to boot from installation disc" I tried putting the image on USB (via http://www.pendrivelinux.com/yumi-multiboot-usb-creator/) and booting it from the USB drive, however the boot menu does not show the Mythbuntu OS as a bootable option.
My computer will boot windows 7 and Ubuntu OS versions from the CD-Rom no problem, I have selected the correct drive to boot from via f12 each time.
I have tried a earlier version of Mythbuntu 10.01 downloaded via torrents and had the same problems. I have even tried installing the 32 bit version.
