Hey – first off, absolutely LOVE Ventoy and been using it for a year now.

I recently got an IODD Mini, and was curious if it was possible to convert an existing Ventoy USB stick to an ISO. The main reason is, I have a lot of small *.wim files and *.isos on my Ventoy and don't want to scroll through 150 images on the little IODD screen.

I tried using dd, creating a 1:1 image of the stick but no success. Unfortunately I don't know much about how Ventoy works on a technical level and couldn't find any documentation about it, so I cannot really figure out on how I could modify the EFI and BOOT folder contents either. Any pointers on how that can be achieved? Would be much appreciated.


PS: Any way to get BitCoin Donations going?

My laptop boots ONLY UEFI.  I have an iso that when used with Ventoy on a usb drive does not bppt (but it does boot when mode is set to legacy on other laptops).  Is there ANY WAY i can get this iso to boot uefi as my new laptop is only uefi boot ?

Thanks for your nice how2

here

It worked for me creating a mint20 vdi.vtoy

which runs perfect from my ventoy usb drive.
Ventoy sees this vdi.vtoy and i can boot from usb menu.

you said to boot from hd

Add a menu like follows to ventoy_grub.cfg, only need to change

Hey,
is it possible to boot an ISO Image in Legacy boot mode using Ventoy started in UEFI bootmode?
And conversely, can I run the ISO image in UEFI boot mode when started Ventoy in Legacy boot mode?
Greetings!

版主，你好！
       我在组装台式机装win7x64和win10x64系统时，Win10有时候点击ISO文件后进去了会黑屏，有时候能正常安装成功，win7就一直不能安装成功，提示缺少驱动器设备驱动程序，win7版是你测试过的“cn_windows_7_ultimate_with_sp1_x64_dvd_u_677408.iso”，Win10版本为“cn_windows_10_business_editions_version_1909_updated_jan_2020_x64_dvd_b3e1f3a6.iso”。请看附件切图

How do I set the root to the correct partition in ventoy_grub.cfg ?

Currently vtoy_iso_part  = (hd0,msdos1)   so    set root=$vtoy_iso_part does not work

It would be better to leave off the parentheses so we can set the root - or is there a better way?

在学校的希沃一体机上，打开软件，插入U盘，U盘的分区成了CDEF，而CDEF是主硬盘的分区。如附件所示。当时看着设备名称和容量正确，就点了安装，结果系统就崩溃了。（提前做了双系统，现在在Win10，日常使用没问题）
当时是win7 x64 专业版。在win10中也存在同样的问题。在自己的电脑上是正常的，如me.png，做好了去学校电脑上，问题仍存在，如附件seewo.png。
自己排除了分区数量问题，在其他班的电脑上同样有问题。

Please help me and fix software

Hi,

配置: 版本1.0.29, EFI引导. 移动硬盘数据分区为ntfs.

尝试了gentoo和debian buster的LiveCD, 启动之后无法挂载数据分区, 错误为Device or resource busy.

现在的Workaround是内核命令行加'toram', 然后启动之后把整个USB Reset一遍 (或者重新插拔).

有没有办法在不加载到ram的情况下也能访问到数据分区的内容 (只读也行) ?

Hi guys,

I am just testing Ventoy and find myself in this situation, for now I just want to be sure this is something that should be working before wasting too much time in something ventoy is not designed to do.

I installed Ventoy on an external HDD using the Linux script. No problems there.

But when I boot in legacy BIOS mode the drive is not listed as an available boot drive. This is how I always set up the system and have used many USB creator in the past.

BIOS settings are correct regarding legacy mode active, boot order, etc. etc. and I was in Legacy mode both times I installed Ventoy on this HDD.

If I switch to UEFI mode the drive is listed and can boot ISO images from there, but only UEFI compatible ones, and that excludes ISOS such as boot-repair-disk and many other tools I normally use.


My question then is if this situation where my drive is not listed on Legacy mode is to be expected or something is going wrong on my side.

Thank you.
