No bootfile found for UEFI!

[bouhlal]

Hello
I have installed Ventoy on my USB and I have added some ISO's files :
MediCAT
Hiren's BootCD
Windows 10 32bit
and windows password recovery BootCD
all give ERROR on HP Laptop :
No bootfile found for UEFI!
Mybe the image does not support X64 UEFI!
Best Regards

[ventoy]

Please give the exact iso file name.
Windows 10 32bit only support IA32 efi, your machine may be x86_64 uefi (amd64 uefi), so this distro can't boot and will show this message.

For Hiren's BootCD HBCD_PE_x64.iso has been tested in UEFI mode.

Besides, you can try a linux iso file, for example ubuntu-20.04-desktop-amd64.iso

I have the same for Memtest86-4.3.7.iso and ipxe.iso but works fine with netboot.xyz-efi.iso (v2.0.17), manjaro-gnome-20.0.3-200606-linux56.iso, Windows10_PLx64_2004.iso and HBCD_PE_x64.iso (v1.0.1) Lenovo Ideapad Z580. evrything works fine with legacy mode

@ventoy I have tested on laptop Lenovo Ideapad Z570 and Memtest86-4.3.7.iso and ipxe.iso gived same error but with additional information:

ASSERT EFI_ERROR (Status = Invalid Parametr)
ASSERT [Ventoy] /home/share/Ventoy/EDKII/edk2-edk2-stable201911/MdePkg/Library/UefiMemoryAllocationLib/MemoryAllpcationLib.c (813
) : !EFI_ERROR (Status)
No bootfile found for UEFI!
Maybe the image does not suport x64 UEFI

netboot.xyz-efi.iso (v2.0.17), manjaro-gnome-20.0.3-200606-linux56.iso, Windows10_PLx64_2004.iso worked fine.
Hope it would helps

@ventoy I still have this error on z580 with ventoy 1.0.16

[ventoy]

@BxOxSxS Please test these ISO files in Virtual Machine (e.g. Vmware) with UEFI mode and to confirm that the ISO file does support UEFI mode.

I checked and they don't work. So it is impossible to get these ISOs to work with ventoy without enabling legacy support in the bios settings?

[ventoy]

Yes.
Ventoy virtualizes the ISO as a cdrom device and boot it.
So if the ISO doesn't support UEFI mode itself, the boot will fail.

Hi All,

I have the same error, I can boot from the same usb, the same iso file and the same Ventoy on asus vivobook but not on asus ROG.

any helpe please

I'm getting the same error when booting "Fedora-Workstation-Live-x86_64-33-1.2.iso" or "pop-os_20.04_amd64_intel_8.iso" on either a new ThinkPad X13 or T14s using Ventoy 1.0.31 UEFI. Secure Boot is disabled in the BIOS on both systems, and the ISO boots just fine if I write it directly to a USB stick with Fedora Image Writer.

Ventoy is able to chain boot Windows 10 (build 2004) just fine on the same systems.

same here on ThinkPad x13 as for @rderooy
EDIT:
It looks like that version https://github.com/ventoy/Ventoy/releases/tag/v1.0.33 fixes issue with my thinkpad. @rderooy try to use newest version

I've been trying on a Dell XPS 13 9360 with Ventoy 1.0.34 UEFI running and Memtest86-4.3.7.iso does not work. Getting the same error as @rderooy

V4 is legacy version. It does not contain efi boot files.

[rderooy]

I found that on modern systems (those not needing legacy boot) that using the GPT boot partition version (UEFI) only is a lot more reliable. With that with recent versions, all seems to work fine.

[eogut]

Thank you both for your replies. Indeed I have erroneously downloaded memtest v4 because I just read ".iso" and went for it. I have used OSFMount to convert the img file of memtest v8 to iso but I have encountered the same issue. ElementaryOS boots just fine. In Ventoy I had enabled Secure Boot and GPT. I cannot boot into Ventoy with Secure Boot enabled on my machine though, it only boots when I disable Secure Boot in BIOS. Would disabling Secure Boot in Ventoy help? Thanks!

Edit: Disabling Secure Boot didn't help. The only thing that changed is that the " No bootfile found for UEFI!" error was now displayed in 1080p. That's an improvement, I guess? /s

You need to make the ISO UEFI64 bootable. You can't just convert things to an ISO and expect them to be bootable!
The easiest thing to do if you don't have a UEFI-bootable Memtest86 ISO is to extract the \EFI\BOOT\BOOTX64.efi file and just copy that to your Ventoy drive. Rename it as MemTest86_64.efi (or something similar).
