On my laptop I tried UEFI and BIOS. In UEFI it would not give an error - it would just ignore the usb stick and go directly into the usual Ubuntu. I take this to mean that in UEFI it is intelligent enough to know that something is wrong, but rather than giving an error, it just ignores the usb stick. In BIOS it always gives the "boot error".
Now on this machine I disabled the boot from UEFI and put the usb stick as the top priority disk. Now, here too it gives the "boot error" message. With 64 bit even the UEFI works properly. Could you please try it on your machine and verify that it is indeed a problem. Otherwise the developers will reach the conclusion that I am doing something wrong and won't know there is a real problem. If Ubuntu posts the 32 bit version as a real option, it should work and not give boot errors. It isn't really fair to say "use the 64 bit version". At this point the problem needs to reach the confirmed stage - or I need to know why it doesn't work for me on any machine I have tried to date. -- 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
