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。

So it's my first time using ventoy, and i was going to install windows ghost spectre os (W10AIOU11.x64WPE+) and all when i tried to boot it in normal mode there's no windows logo, it only shows a beeping underscore mark on the top left of the screen. I tried to boot it on wimboot mode and it says "FATAL: no bootmgr.exe" but after i checked the iso file everything is there. So i try to run it using compatibility mode and this time it worked but i can't install windows from here since it not recognized my hdd. What's the problem here? Is it because the WPE+ thing? Do i need to download the normal version?

目前使用上功能都正常，先感謝作者！這邊有個功能建議，不知道是否能實現？

目前處理映像的方式，都是透過手動放入iso資料夾後，再到管理介面重新載入映像列表，是不是可以新增上傳功能，讓網頁端就可以直接加入新的映像，這樣一來會方便許多！

我自己的使用方式，是在Linux主機中將iVentoy以系統服務的方式運作(再跟OpenWrt掛在一起)，平時都是從Windows下的瀏覽器進行操作，若可以加入上傳功能，就可以不用再另外透過SCP複製映像到Linux中，減少一個困擾～

除此之外，若是可以上傳，也希望加入刪除功能，這樣一來會更完整（當然，前提是運作iVentoy的使用者有刪除檔案或軟連結的權限）

之前做好的多套linux系统，包括深度、优麒麟、还有batocera游戏等，用ventoy在多个笔记本、台式机上都能正常运行，但是在新配的华硕z790+i7-14700kf平台上，所有的linux核心的系统都无法成功启动，都卡死，请问大家有没有类似的经历，是ventoy的问题还是linux系统和新平台的兼容问题？
好像启动时都提示一个AHCI控制器有问题，不知道是个体问题还是兼容性的通病，BIOS恢复出厂设置等都试过，也试过一些选项的变更，都无效。

Hello,

   I have PXE boot working with iVentoy, but boot of SystemRescueCD fails because media isn't found after kernel load. I expected this because it's normal for the kernel to not have access to the PXE virtualized media after loading. I've solved this in other PXE environment by adding kernel parameters to point to HTTP location for media. In iVentoy, I tried to solve this with file injection, but there isn't enough documentation on the file injection feature to understand how or where in the boot process the injection happens. Is there a better way to get this ISO bootable over PXE with iVentoy?

It has been a few months since I gave up trying to get vtoys to work in eufi mode.
Software has updated since then so I thought I would try again. I created 6 different Linux distros following the instructions on the ventoy site. I created new virtual machines using virtual box.
EFI enable True, fixed disk.
Once the OS rebooted I ran the vtoyboot script. I then shut it down. Then copied the vdi to ventoy renaming the suffix to vdi.vtoy
Not a single one worked in eufi mode. All I get is an unblinking cursor at the top left of my screen.
I have tried this on a pure ventoy drive as well as ventoy on easy2boot with the same outcome.
5 of the 6 work fine in Legacy mode (kubuntu, Ubuntu,MX,fedora,Bodhi).
PopOS does not work in either but I was warned when running the vtoyboot script on Pop that it would only work in eufi.
The only reason I chose 6 was to hopefully get a couple that would work. I do not know what I am doing wrong.

Thanks in advance.

比如我在公司用 iventoy 搭一个服务器，配置好各种安装镜像和无人值守的脚本，给客户只要安装一个 ventoy，然后配置好客户那边的 ventoy（指定我的 iventoy 服务器地址）让它启动后在机器能连接外网的情况下直接通过访问 iventoy 服务器转入 PXE 启动流程，全过程不需要用户干预就能完成系统安装。

请问 ventoy 能实现这样的功能吗？

I have a problem when i try to boot PXE from Old PC with Legacy BIOS. I take this error message (image). 
I have used Extrernal Net settings because iVentoy server and the third-party DHCP Server are located in different LANs/VLAN.
I would like to inform you that if I use PC with UEFI all work ok. Could you help me?

I've tried adding the autounattend to both the root of the ventoy drive (have not tried the ventoy boot partition yet just the iso data partition) and the root of the DVD iso file.  Both methods work without using ventoy but fail when using ventoy.  Am I doing something wrong?  I have added Windows PE configuration pass settings and need the answer file to load with the boot environment.  Would loading a command prompt from within the windows PE environment and specifiying the answer file work if the answer file was on the ventoy data partition?  Tried searching the forum but looks like json editing is in order.  Is this correct?  Thanks in advance for any help.
