I have an Acer Switch 10 with a 32-bit UEFI. I installed 32-bit UEFI GRUB and was able to boot 64-bit Ubuntu. It definitely was not 32-bit Ubuntu - I was specifically using a 64-bit installer/LiveCD.
I can confirm definitively that a machine with 32-bit firmware can absolutely boot a 64-bit operating system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1341944 Title: 32-Bit UEFI bootloader support needed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1341944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
