As a new member and user, I am very pleased with Ventoy. It is absolutely magnificent.

I have found this issue when using Ventoy on my Toshiba 500GB SSD. As per the title, the VENTOYEFI partition is not visible on this SSD in Windows File Managers - but it is there!. The SSD boots and works just fine and the VENTOYEFI partition IS visible in WinPE applications.

When I use Ventoy to set up various other Flash Drives, I see the VENTOYEFI partition on those flash drives in Windows file managers - but not on this SSD?

Any thoughts?

1st test > iventoy 1.0.19
Asus router as DHCP server ( no advance setting for nextserver and bootfile )
All settings are default except > DHCP server : External / Externalnet ( I tried both)
Gives error : No boot device found ( both Bios and UEFI mode)

Only way to get it work is to change DHCP server setting to " Internal"

I am using AIOboot PXEboot from more then 5yrs
Same network setup. Pc boots without any problem.
( All Pc I clone or repair with this PXE setup)

Please check image for detail.

I think something is missing in iventoy to work with external DHCP without any advance settings.

Hi @ventoy
A user asked how to install iVentoy on a Synology NAS drive.
I couldn't find an answer because I don't have any knowledge on this subject. Can iventoy be used on this device?
if it is possible How can we do it?

(sorry, translate with google)

Start the ISO on a USB stick with Ventoy.
In the next menu only 'Boot in memdisk mode' works for Truecrypt (TS).
Truecrypt-Rescue starts.
If the Truecrypt|Windows-Loader is then restored with F8, the query comes from TS:  Disk 0?  y/n
After y(es) the loader is written to the disk 0, but it's the USB-stick! Of course, after that the stick no longer boots and the TS-drive was not updated.
For CDs, TS does not mix up hard drives, the first real hard drive is used. 
In the BIOS I can define the USB stick as a CD, but Ventoy no longer boots as a CD.

The Ventoy stick should somehow be recognized in the system as a CD (or as a Not-Harddisk-Thing) not as a hard drive. 

Then TS would do everything right.

Greetings,
I'm trying to add ventoy to my Ubuntu grub menu.
My ventoy is installed on a 2nd ssd drive on my laptop as sdb.
My /etc/grub.d/40_custom file is:

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry 'Ventoy Boot USB' {
insmod part_gpt
insmod ext2
insmod fat
insmod exfat
insmod ntfs
insmod chain
search --no-floppy --set=root --fs-uuid 8CC4-D433
set search_efi_path=(hd1,2)/ventoy
# chainloader /dev/sdb2/ventoy/ventoy_x64.efi
chainloader (hd1,2)/ventoy/ventoy_x64.efi
}

I've run update-grub and when I boot I see ventoy on the grub list:
But when I run it I get"
"Invalid signature"

What am I doing wrong?

Hello,

I have a problem. I cannot get my icons visible for my ISO files. I use a 128 GB Philips USB 3.1-3.2 formatted in exfat. The icons are in the folder Ventoy - Theme - Vimix - Icons. I don't see what is wrong. Everything seems to be correct.


can anyone help me thank you

I seem to be having a strange issue when booting iVentoy using UEFI mode. I'm unsure if it a bug or if I'm missing something but for example when booting a stock Windows image using iVentoy in UEFI, I end up with a garbled image.

I have tested this on multiple physical machines and also using Virtual box. Unsure if it's related or not but when booting the same image in UEFI mode using Ventoy (USB version) everything works fine. When testing on Virutalbox in UEFI mode it hangs at the message "Preparing for boot, please wait..." and then eventually restarts.

My iVentoy server is running as a Proxmox virtual machine (Debian 12) in a different VLAN than my PXE clients. I am using iVentoy in the "ExternalNet" mode with OPNSense being my DHCP server (I have network booting enabled & allowed through Firewall), but I have also tried changing this to "External" and even using the built in DHCP server on the same subnet. I also tried the Windows version of iVentoy but all yield the same garbled image.

Interestingly booting a Linux based ISO in UEFI mode seems to work ok (I tried GParted).

I can reach the iVentoy menu fine, but when I select an image I get the garbled image.

I have attached some images to help explain things, although I can only attach 5...

• Image 1 - UEFI Windows boot using Ventoy USB version (Works)
  
• Image 2 - UEFI iVentoy boot (Can access menu fine)
  
• Image 3 - UEFI Windows boot using iVentoy (Garbled image)
  
• Image 4 - UEFI Windows boot using iVentoy with Virtualbox (Hangs at message screen, then restarts)
  
• Image 5 - UEFI Linux boot using iVentoy (Seems to work fine)
  
• BIOS Windows boot using iVentoy (Works)
  
• OPNSense DHCP network booting options (Next server = iVentoy IP address, BIOS image name = iventoy_loader_16000_bios, UEFI image name = iventoy_loader_16000_uefi)

我的无人值守文件 自己单独放进做好的isou盘里面就没问题，可以正常自动安装，但是放进ventoyu盘里面，无人值守就会报错，提示无法找到windows文件夹，iso文件和无人值守文件都是一样的，单独测试过iso和无人值守文件 都是可以的 ，有没有大佬帮我分析一下，我已有重新制作过ventoyU盘，也换了最新的ventoy版本制作，实在是找不到问题在哪，但是我的iso文件和无人值守文件单独用有没问题，所以才来到论坛求助，请大佬解答

Hi everyone!

I've been using Ventoy to boot all my ISO installers, it's very useful!
I'm having a problem with the Devuan 5.0 netinstall though. After the preamble phase, I get this error:

现在大量嵌入式的linux使用img.gz格式的镜像，比如软路由openwrt，iStoreos等现在都放弃了iso格式的。我试图用gzip解压成img使用，我自己测试有的能解压，有的不能。解压后能刻盘使用，但是在ventoy却不能使用，会一直卡住，就一个光标闪烁。总之不管能否解压成img，在ventoy里都没法使用。
另外，大神对镜像的结构比较了解，能否出一个工具，可以从启动U盘提取iso镜像。找遍全网，没一个能用的。有个powerISO能够提取img格式，但是，如果你u盘容量很大，比如64G，那就悲催了，哪怕真正的启动分区只占用几百兆，img也有64g那么大，不能自动把未分区的空间删掉。并且提取了也不一定能用。强烈建议出这么一个工具，能够把任意启动盘转成ventoy可启动镜像，就太方便了。这个工具出了一定大力赞助。
