  [SOLVED] iVentoy 1.0.36 - Auto Install Script (autounattend.xml) stopped working
Posted by: matmus06 - 06-29-2026, 07:38 AM - Forum: iVentoy Discussion Forum - Replies (4)

Hello,
After updating to iVentoy 1.0.36, the Auto Install Script feature no longer works.
What worked before:

  • iVentoy 1.0.35 → everything works perfectly
  • Same Windows 11 25H2 ISO
  • Same autounattend.xml file
Problem with 1.0.36:
  • The script is correctly added to the ISO in the web GUI
  • It is set as Default Auto Script
  • I tested with multiple different XML files (including minimal ones)
  • Tried with and without Auto Script Select Timeout
  • File is named autounattend.xml (UTF-8)
Despite all that, Windows Setup ignores the unattended file and runs in normal (manual) mode.
Environment:
  • Windows 11 25H2 ISO
  • iVentoy 1.0.36 (latest version)
  • Server running on Linux Debian 13
Tests done:
  • Downgrading to 1.0.35 immediately fixes the issue
  • Removed and re-added the script multiple times
  • Tried renaming to unattend.xml
  • Restarted the iVentoy service after every change
Is anyone else experiencing this issue with version 1.0.36?
Is this a known regression or an intended change?
Thank you in advance!

  Using ks script issues
Posted by: Niesitelin - 06-29-2026, 07:08 AM - Forum: iVentoy Discussion Forum - Replies (2)

When I used the automated deployment script from iventoy for installation, I encountered two issues. One was that several versions of CentOS 7 could not detect /dev/sr0, preventing me from proceeding with the installation process, as shown in Figures 1 and 2. The other issue was that several versions of CentOS 8 prompted me with a network unreachable error, preventing me from proceeding with the installation process. However, after entering emergency mode, I was able to ping normally, as shown in Figure 3;

By the way, I tried to use the kickstart7.cfg file in the example/ directory for CentOS 7.0 installation, but it also failed to install properly.

When I don't use the ks script for installation, it loads normally. Could it be that there's a problem with the ks script I wrote? Or is there some other reason? Could you please help me out.

Bug Ventoy Plugson bug
Posted by: VadimChoi - 06-25-2026, 03:07 AM - Forum: Ventoy Plugin Forum - Replies (5)

When I try to change Secure Boot string to Bypass Secure Boot (means 0) Plugson just removes whole string and if you select follow UEFI Secure boot check then it will return but with option 1 and also with Secure boot disabled I cannot boot entirely. Also VTOY_WIN_UEFI_RES_LOCK resets when entering Plugson. Why developer not testing it before release??

  Update needed for 2023 certificates ??
Posted by: Epictetus77 - 06-21-2026, 11:59 PM - Forum: Ventoy Discussion Forum - No Replies

Will Ventoy need to be updated to rely ONLY on 2023 Secure Boot certificates when MS revokes the 2011 certificates?

  External DHCP
Posted by: valstar - 06-05-2026, 07:11 AM - Forum: Ventoy Discussion Forum - Replies (1)

I have now inventoy 1.0.34 running only it does not work anymore (also the 1.0.26 does not work).

I think this is because the IP address given by the third party (the router) is a.b.c.20 for example while iVentoy only respond to ip address a.b.c.201 till a.b.c.221.
(I saw in WireShark the IP address given to the PXE Interface).

The DHCP server is in the same subnet (a.b.c.1/24) , On this DHCP server I configured option 66 and 67 (bootfile and next server).
I see that the PXE interface gets it's IP address but not within the configured range, even if I bind the PXE mac address to an IP address within the range it still doesn't work.

Looks like the iVentoy server does not respond at all? In the firewall I permit all traffic to and from the program 'iVentoy_64.exe'
The iVentoy is running on a Windows Server 2016.


Waiting at your input.

Kind regards,
 Johan

Question Regarding UAPI.1 usage for multi-booting ISOs
Posted by: splayer - 06-05-2026, 05:20 AM - Forum: Ventoy Discussion Forum - No Replies

Hello, I have been trying to find an easier alternative to implement the multi boot ISOs. I believe we can use UAPI.1 (The Bootloader Specification) to our advantage if we add two new keys to the conf file. I have also made the proposal to add those keys in the official github discussion thread for UAPI. I have written a detailed blog on how this will solve the need for hardcoded configs for each distribution. I will highly appreciate if the Ventoy dev takes a look at it and provides feedback on what I am trying to achieve. The blog is: https://splayer.4plt.ch/blogs/2-the-vent...index.html
I am also looking for feedback on the correctness of the facts I have presented in the blog. 
If this is not the correct place to post this then I sincerely apologize and request to guide me to a proper channel. 
Thank You.
