UEFI only system

ecrofeht

I am attempting an install on a lenovo stick pc. It only supports UEFI boot. I have disabled secure boot but it still does not see the usb as bootable. Can this OS boot UEFI?

ecrofeht edit: I searched the Lenovo forums on Ideastick 300 and it needs to use "boot from file" option and search for a 32bit UEFI bootloader usually located at \EFI\BOOT\bootia32.efi file on the batocerausb's root, but this file isn't currently built into batocera. The other possible problem arises if and when it it gets built for this architecture is that it won't be able to see the internal eMMC mountpoint /dev/mmcblk01 without additional patching. I don't know if @nadenislamarre would be ready and willing to add this in.

What version of batocera did you download? Try the test version.
What version is your Lenovo stickPC? Check model number. Post it here.

I would however think it's your stick pc, It doesn't have the bios programming to keep the USB port powered on boot.

You could try this. Have 7zip installed or something to open and extract *.IMG files.

Download both the 32bit copy and the 64bit of batocera
Prepare the 64-bit batocera onto usb drive (I'd hope on a another computer, although I suppose you could try use Rufus on windows on the stick https://rufus.akeo.ie )
Download https://github.com/jfwells/linux-asus-t100ta/blob/master/boot/bootia32.efi and paste into the \EFI\BOOT\ folder of usb
Reboot stick with batocera edited usb, Try booting from "boot from file" option and search for the \EFI\BOOT\bootia32.efi file on batocera usb. ##This is hoping the EFI 32bit will boot 64bit kernel##
hope it works. if it doesnt, it was a good idea that failed.
optional: try again, but this time Extract /boot folder from 32bit batocera.IMG (from 7zip etc) and replace the whole boot folder in 64bit batocera usb. ##This is hoping the EFI 32bit will boot 32bit kernel##
optional: figure out way to build your own 32bit UEFI compatible bootloader and build your own batocera.

The pileup mess made after connected powered usb hub and extras like usb wifi/bluetooth/controllers because the linux kernel doesn't have firmware patches for the stick's wifi/bt etc, makes these compact PCsticks kinda like ironic toys. Compact Windows PC but messy Large DoItYourself Linux setup. You throw it away when it overheats beyond repair.

hi.
uefi is supported on both 32 and 64 bits.
it works while i use it to boot.

however, your computer is looking for bootia32.efi which seems to be uefi32bits
which is not supported on batocera (in fact, i didn't know it existed).
you should just try to download bootia32.efi from an ubuntu server and place it in efi/boot. i guess it may be enough. not sure.

I know this is a very old post but I came across it because I was also having trouble getting Batocera to boot from USB on a UEFI system. For anyone else Google sends this way: the solution I found is to create the USB using Win32 Disk Imager. When I used either Rufus or Balena Etcher the USB would not appear in the boot menu but when I used Win32 Disk Imager it did.

But what if you are on an Ubuntu/Linux or macOS machine trying to make an installer medium for a UEFI BIOS machine (HP EliteDesk tower rocking AMD chipset in this case)?
