We need to ascertain what is causing the problem first. Yes, the 32 bit install works fine for most people.
dd is a command to copy data around. Assuming the usb stick is /dev/sdb, you can use it to copy the iso image to the stick with: sudo dd if=ubuntu-etc.iso of=/dev/sdb Make sure it really *is* /dev/sdb before doing this, and note that this will wipe out all files on the usb stick, but this method may work for you. If it does, then it indicates there is something odd about your bios that is tripping up syslinux. If not, at least grub has a command line that we can use to further identify what is going wrong with your bios and see if it can be worked around. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1512811 Title: 15.10 32 bit download gives error when run from usb To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1512811/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
