What happened?

I am able to boot the latest Debian, Devuan, FreeBSD, and NetBSD install ISOs just fine. The latest install ISO of OpenBSD fails to boot, giving the following message.

No bootfile found for UEFI!
Maybe the image does not support x64 UEFI

This happens with both legacy BIOS and UEFI modes.

This is the SHA256 hash: fdf1210ffe87213eeca5f1d317e8b19364cbae83545cdfc7845098a53fc79a60 install73.iso

Here's what's in the partition for boot images:

debian-12.0.0-amd64-DVD-1.iso
debian-12.0.0-i386-DVD-1.iso
devuan_chimaera_4.0.0_amd64_desktop.iso
devuan_chimaera_4.0.0_amd64_netinstall.iso
devuan_chimaera_4.0.0_amd64_server.iso
devuan_chimaera_4.0.0_i386_netinstall.iso
FreeBSD-13.2-RELEASE-amd64-disc1.iso
install73.iso
NetBSD-9.3-amd64.iso

Is the problem with the .img file (as in the link you gave) or the .iso file? Do you get the EFI message when you legacy boot the file? I cannot see any EFI boot files in install73.iso. It only seems to support legacy booting. Try the .img file?

[DavidGriffith]

I get the same message when I attempt to boot the .iso in either legacy or (U)EFI modes.

I can confirm that there is the exact same problem with OpenBSD 7.4 iso.

[steve6375]

Exact ISO filename please?

It does not seem to contain UEFI 64-bit boot file \EFI\BOOT\BOOTX64.EFI - so it won't UEFI64 boot -even if ISO is used as the boot DVD in a virtual machine. It boots OK in legacy mode for me though in VBox under Ventoy...

[DavidGriffith]

I just now tried booting OpenBSD 7.3 and 7.4. Both booted without complaint and gave me Welcome to the OpenBSD/amd64 7.x installation program. The big difference this time seems to be that I upgraded Ventoy to version 1.0.97. Could I get some people to verify this?

@DavidGriffith Months later, but I just installed OpenBSD using the iso through Ventoy and it worked fine.
