| Failure when booting Ububtu 20.04 in Secure Boot |

I am running Ventoy 1.0.53.
I just got my Ventoy USB drive working with Secure Boot. It was painful to get the MOK keys registered, but I finally figured out a work-around (Not Ventoy's issue, I know).
Now that I have my Ventoy USB working with Secure Boot, I started trying out all my ISO images to see how they ran.
I ran into a problem with my Ubuntu 20.04 ISO with a persistent image enabled.
When booting Ubuntu 20.04, I saw the following MOKManager failure:
Verification failed: (0x1A) Security Violation
Is this a known issue with Ubuntu and Secure Boot?
Thanks,
AzJazz

| Problems booting VDisk on UEFI-only notebook |

Hi!
First, thanks a lot for developing this innovative USB boot tool.
My goal is to create a bootable USB drive with a customized Ubuntu Linux 20.04 based on VirtualBox images. It shall work on a (quite recent) Notebook
model called Tongfang GM7NG0R (https://noteb.com/?model/model.php?conf=...299&ex=USD). It is the first notebook I have which has no legacy boot support (so UEFI only, but secure boot is disabled).
What I did: I downloaded the Ubuntu ISO (ubuntu-20.04.3-desktop-amd64.iso) and installed it into a fixed-size VDI image as described on the "Linux vDisk Boot Plugin" page. EFI mode has been activated before installation, and the most recent vtoyboot script run. When I boot the USB and select the *.vdi.vtoy image, I see a short black screen and then the system immediately restarts. However, booting the exact same image (on the same USB drive) works fine on other Legacy Boot notebooks, and also on one other UEFI boot machine. Interestingly, on the "problematic" Tonfgang notebook, it is possible to boot the original Ubuntu ISO file using Ventoy.
What could I do to "debug" or resolve the issue? Any help to boot a vDisk on this notebook would be appreciated.

Using this ventoy_grub.cfg:
Code: menuentry "Boot Mint (Xfce)" {
set my_vdisk_path="/Virtualbox/LinuxMint(Xfce).vdi.vtoy"
if search -n -s vdiskhd -f "$my_vdisk_path"; then
vtoyboot_common_func "($vdiskhd)$my_vdisk_path"
else
echo "$my_vdisk_path not found"
fi
}
then after the first menu loads, which says it couldn't find any ISOs, I can press F6 and then boot my vdisk from there, either from the USB stick or the computer's HDD (which is obviously faster). That works but I want to skip straight to the second menu.
I created this ventoy.json:
Code: {
"control": [
{ "VTOY_DEFAULT_MENU_MODE": "0" },
{ "VTOY_FILT_DOT_UNDERSCORE_FILE": "1" },
{ "VTOY_SORT_CASE_SENSITIVE": "0" },
{ "VTOY_MAX_SEARCH_LEVEL": "1" },
{ "VTOY_MENU_TIMEOUT": "10" },
{ "VTOY_DEFAULT_KBD_LAYOUT": "QWERTY_UK" },
{ "VTOY_FILE_FLT_VTOY": "1" },
{ "VTOY_DEFAULT_IMAGE": "/Virtualbox/LinuxMint(Xfce).vdi.vtoy" },
],
"image_list": [
"/Virtualbox/LinuxMint(Xfce).vdi.vtoy"
"/Virtualbox/LinuxMint(MATE).vdi.vtoy"
]
}
but it says "syntax error detected" when I boot with that. Can anyone see what's wrong?
Also, I'd like to try booting my vdisk on my PC from my grub4dos boot menu, without needing to use a USB stick, but it seems I need vdiskchain and it doesn't seem to be available anywhere to download, only if you can compile it using the files here https://github.com/ventoy/vdiskchain which I don't know how to do. Is there anywhere I can download it?

{ "VTOY_DEFAULT_IMAGE": "/Windows_7_Pro_x86_x64_11.08.2021.iso" }
],
"theme": {
