Hello.
I'm trying boot Windows7_Pro_SP1_Polish_COEM_x64.iso with Ventoy 1.0.09 and 1.0.10 and I have this communicat (error) after booting (see screen below).
My settings:
- BIOS with Legacy support/Legacy first
- of'coz boot with USB device (USB GOODGRAM)
- I see Press any key to boot from CD or DVD...  (screen 1) - of'coz any CD/DVD not inserted to the CD drive
- after this normally screen with Loading files...
- click Install now
- after this I have error (screen 2) - translate from Polish language: winpesshl.exe - drive not found. In the drive not inserted disc. Insert disc do the disc drive\Device\Harddisk1\DR1/

I tested this ISO on VirtualBox and with Rufus 3.9p/3.10p and all works fine, I don't have any error with boot and normally installed. I tested it with many laptops like Asus, Lenovo, old Fujitsu-Siemens...

Sorry for my English.        

So far it seems to work only with single partition.

What if I want to do this on a USB-HDD where I want the first partition with specified capacity for the ISO files and rest of the spaces for other consumption purpose in separate partition.

Is it possible in future?

Hi.
I tested with Ventoy 1.0.09 BackBox Linux 7 amd64 - preview 05.2020 (backbox-7-desktop-amd64.iso).
"Backbox Linux is a an Ubuntu-based distribution, it is designed to be fast and easy to use (...)".

It's only THE BEST software that can do the JOB very well as it's supposed to be.
I knew one Hardware that does the same job but it costs money.

And this Ventoy Software gave us soooooo much of relief!!!

Only one request to make, is it possible to BOOT from WIM file likewise it does for ISO?

If not then what could be the best & easiest way to CONVERT from WIM to ISO?

If this gets done, then this Software would be a Huge revolution in the Live-OS segment.

我发现自己常用的几个WinPE ISO都是要开启Memdisk模式才能正常启动的，而Memdisk模式默认是关闭的。

建议增加一个小功能：对于任意ISO比如A.iso，如果同目录下同时存在特定的标识文件例如A.iso.mem，则在A.iso被选中时自动开启Memdisk模式，不用手工按F1切换。

主板华擎Z390太极，BIOS版本4.30（官网最新），安全启动开启，CSM关闭。
ventory版本1.0.09-windows，制作时勾选了"配置选项" > "安全启动"。

参考《UEFI模式安全启动操作说明》进行到Perform MOK management这步，选Enroll key from disk回车后，不能显示预期的Select Key画面，电脑不再响应任何键盘输入，键盘大小写切换键和数字锁定键都不能切换相应LED指示灯状态。疑似死机或陷入死循环。

使用两个不同型号的U盘制作和测试了多次，100%重现。

hi!
thanks for this great tool.
i've noticed that it runs a lot smoother, when i disable the theme (comment in grub.cfg)
is there an "official" way to disable theming?

Hello,
I'm trying to boot "manjaro-lxqt-20.0-minimal-200423-linux56.iso" on a HP8570p in BIOS mode with "ventoy 1.0.9"
I can select the iso and I got the manjaro screen.
Then I just pressed enter to start the manjaro live cd. After a while I got this message:

I tested boot with Ventoy:
1. Manjaro Linux_KDE -20.0-200426_linux56 (x64)
2. Manjaro Linux-xfce-20.0.1-200511-linux56 (x64)
