Everything that follows is 64 bit...
I successfully replaced Windows 8.xx on a new Toshiba with Ubuntu 14.04 LTS by installing from live USB stick created on that machine. In creating the original live USB stick the software seemed to recognise that the live version was to be run on an EFI machine, so problems in installing from the stick to the machine itself were relatively minor.
I'am trying to install Fedora on a new 64bits machine that I acquired yesterday. As I explained here, I am unable to boot on any version of Fedora: After installing the OS with a Live version and reboot, no OS is detected by the BIOS. I tryed with a first computer (LENOVO 64bits i-Core5) that I returned to the vendor.
Boot from USB stick halts "syslinux 4.03 2010-10-22 ..." and flashing cursor.
Attempting to run USB live 11.10 x64, also tried natty and kubuntu 11.10 same results.
