I live far out in the sticks. I am able to get in town to a Internet connection only sporadically, perhaps once every 7 to 10 days. I will be leaving soon and cannot come back to get online for at least a week.

After waiting a couple hours to download the latest Fedora Live Gnome, I used the liveusbcreator on windows to burn the iso to live usb.

There is no UEFI boot loader.

The F18 x_64 version will not get past the UEFI key check.

Computer recognizes USB stick on boot, but will not boot from it.

No matter what I do, it just boots into windows.

I am aware of all the UEFI BIOS options. Disabling secure boot does nothing. Even selecting the USB drive on boot leads right into Windows.

The Bay Bridge processor is billed as x_64 but runs 32-bit Windows 8.1. I cannot get the 64 bit Fedora to boot even though it has EFI boot loader in the distro.

Do not ask me if I checked options in UEFI. There is no option to bypass key signing and verification. There is no option to turn off fastboot. UEFI is ignoring the "bootable" USB and going straight to Windows boot loader, even when I put the USB first in boot order.

I have been reading several dozens of articles, and have tried hours and hours of configurations to try to just get the darn liveusb to boot. No dice.

I am reading articles all over how this has been a known issue since at least 2010 and Linux communitarians, after much lip service, have done little to address it.

I await tons of non-sequitur questions rather than solutions, to just make me give up and hail Microsoft.

Is there a way to make this system boot the live USB?

Is there a way to use the x_64 EFI boot loader to boot a 32 bit live image?

The Asus T100TA only supports a 32bit EFI boot loader, even 32bit Linux distros use a 64bit EFI boot loader, so its currently not possible to boot a standard Live image.

Its not worth the trouble right now anyway as no current distro supports the T100 hardware properly. They do not support its WiFi, sound or graphics. This will hopefully be resolved in the next release of a big distro as the very latest kernel is starting to get support in. For now, we are stuck with Windows.

I would not expect 32 bit UEFI support in the next release. Very few devices were made with it, and mostly all were made well in the past. The UEFI implementation as described sounds quite flawed and even broken; unless someone volunteers to write and test the code, or Asus ships a firmware update to fix it, the situation will probably not change.

Except they weren't all made in the past, the brand-new Atom tablets are being built with it. I'm pretty sure this problem is not unique to the Asus, I believe its standard for the Bay Trail tablets. Dismissing them as too niche to care about would be foolish - these things are selling like hot cakes.

I would say that using a 64bit UEFI on the 32bit builds of the OS is far more illogical.

It turns out someone did do some work towards making Fedora work on Bay Trail tablets ! See https://www.happyassassin.net/fedlet-a-fedora-remix-for-bay-trail-tablets/ , and buy @AdamW a beer if you see him around.
