Description: It displays the menu: I choose the first item, the menu disappears, and nothing happens.

The image was written to the USB drive with dd.

I made it work by removing the partitions, and adding a vfat one with label ARCH_202006. Then I copied the files from the iso image. This way it works.

I guess it has something to do with xorriso:

Is there anything I can check or confirm?

Additional info:
* archiso 44-2
* archlinux-2020.06.01-x86_64.iso
* libisoburn 1.5.2-2
* UEFI motherboard

Steps to reproduce:
* dd the official image to a USB drive and boot
This task depends upon

I just tried to reproduce it (make it work by recreating the partition, and copying the files), and failed. But I've found another way: write the official image, but not let it run EFI/boot/bootx64.efi. Run EFI/boot/loader.efi. Which probably means that something is wrong with /usr/share/efitools/efi/PreLoader.efi:

And it seems to be easy to build:

Could it possibly has something to do with disabled Secure Boot...

Further testing revealed that the official image works sometimes. But loader.efi always works (it didn't fail so far). And not sure if relevant, but every boot starts with:

[ 0.81296] DMAR: [Firmware Bug]: No firmware reserved region can cover this
RMRR [0x000000008d800000-0x000000008fffffff], contact BIOS vendor for fixes
:: running early hook [udev]
Starting version 245.6-7-arch

I tried to add a couple of print statements to PreLoader.efi, but that didn't produce any tangible results.

PreLoader.efi in archiso is just a waste of space, so this issue could be "fixed" by  FS#59487  .

Thanks, I posted a patch there. From what I can see with the patch it always works.

P.S. Just in case. A forum post with which it all started:

@x-yuri: Does this work with the 2020.07.01 image for you?

@dvzrv yes
