Good morning, I have a request, if possible.
On my Ventoy USB drive I use a folder structure, for example:
Code: /ISO/Windows
/ISO/Linux
and so on.
I also created a folder called Misc Software, where I keep Windows executable programs, video guides, DOCX documents, and much more.
I would like to know if it is possible to view its contents when booting the USB drive with Ventoy.
Please note: I only mean viewing the files, not running them. I am aware that I can view the contents simply by opening the Misc Software folder, but to do that I need an operating system to be running.
So, if I need to check what the above-mentioned folder contains, I can’t do it directly from Ventoy.
I would like to know if there is a procedure to do this; otherwise, thank you anyway for reading this far.
Thank you.

I have a router running the DHCP server and I want to use dnsmasq as a DHCP proxy for iVentoy.
The router has the address 192.168.1.1 and gives addresses in the range 192.168.1.x
The dnsmasq server runs on Ubuntu and the iVentoy server runs on Windows address 192.168.1.102
The following config does not work:
port=0
log-dhcp
dhcp-range=192.168.1.0,proxy
pxe-service=x86PC,"Test",iventoy_loader_16000,192.168.1.102
dhcp-no-override

| QEMU + Ventoy USB: UEFI boot always drops to EFI Shell instead of auto-boot |

Post (English – faithful translation)
Hello,
I am trying to boot a Ventoy USB drive in UEFI mode using QEMU with OVMF, but QEMU always drops into the EFI Shell instead of automatically booting Ventoy.
What works - The Ventoy USB boots correctly on real hardware in UEFI mode
- The Ventoy USB boots correctly in QEMU using Legacy/BIOS mode
- From the EFI Shell, manual boot works:
fsX:cd EFI\BOOTBOOTX64.EFI
- After running this, Ventoy starts normally.
What does NOT work- Automatic UEFI boot when using QEMU
- Even when using:
- startup.nsh
- placed in the root of the USB
- Clean or regenerated OVMF VARS files
- Passing the USB drive directly as a raw block device
QEMU still always boots into the EFI Shell.
Environment- Host OS: Linux
- QEMU:
qemu-system-x86_64
- UEFI firmware:
OVMF_CODE_4M.fd
- +
OVMF_VARS_4M.fd
- USB drive passed as a raw block device
- Standard Ventoy layout (GPT with EFI partition)
Minimal QEMU command (manual boot only works)
Code: sudo qemu-system-x86_64 \
-m 2048 \
-drive if=pflash,format=raw,readonly=on,file=/usr/share/OVMF/OVMF_CODE_4M.fd \
-drive if=pflash,format=raw,file=/usr/share/OVMF/OVMF_VARS_4M.fd \
-drive file=/dev/sdX,format=raw
Question
Is this a known limitation or incompatibility between:- QEMU + OVMF
- and Ventoy UEFI boot from a USB device?
Are there:- recommended QEMU settings for Ventoy UEFI boot?
- known workarounds (other than manual EFI Shell boot)?
- an explanation of why OVMF does not automatically detect
BOOTX64.EFI
- on the Ventoy USB?
Thanks in advance for any clarification.

w我在使用ventoy安装操作系统的时候,通常都是用无人值守的配置文件进行硬盘的重新分区。在不同电脑上硬盘会有不同的配置,尤其是有时候有些电脑会同时具有机械和固态。经过大量测试,我发现使用这个VT_WINDOWS_DISK_CLOSEST_400参数一般都可以准确选择到固态硬盘.但是这个参数有个潜在的风险,他不会避开ventoy所在的U盘。我遇到过不止一次,使用自动安装配置文件后,ventoy自身被删除了。比较常见的原因是主板开启了vmd等需要额外安装驱动的情况。这个时候就比较无语,因为这意味着我需要重新制作一个ventoy的U盘,实际使用中还是要浪费不少时间的。
有没有办法能按照磁盘大小选择磁盘,同时还能避开ventoy自身呢?实际上就是想达到VT_WINDOWS_DISK_1ST_NONVTOY 和 VT_WINDOWS_DISK_CLOSEST_400两个参数配合的效果。
