When you download and extract the file, it’ll give you a list of devices. The contents of the device will stay untouched after each installation. In this case, you can copy and paste them to your USB device and boot directly from it.Īnother way Ventoy makes booting more convenient is by letting you transfer numerous images to the USB. Typically, you’d need to unzip ISO files before launching an installation. The only drawback is that you can’t use it for non-ISO installations. It’s open-source, free, and supports over 260 ISO files. Ventoy represents a new generation of ISO burning apps. The concept of "Ventoy Compatible" is introduced by myself and I hope that it can be widely supported someday.This new software application takes a different approach to OS booting, facilitating the process and making it more flexible. If it contains the process mentioned above. I call such an OS distro or iso file as "Ventoy Compatible" Ventoy gives some ways for the OS distros to chose to mark themselves. Ventoy will no longer need to do the boring hook.Īnother thing is that how ventoy knows the OS in the iso file is "Ventoy Compatible" ? So things will become very simple if the OS distros integrate this tool and do the compatible processing. Of course the tool will get nothing if they were not booted by ventoy, in that case they can go as originally.
In this way, the OS can know that they were booted from a virtual disk created by ventoy and can also know which iso file in which disk is the right image.īased on that, the OS can find the source medium successfully and continue to boot. In fact, ventoy saves the information to runtime memory before booting and provides a tool to get the information. But the hook is really a hard work because there are so many different OS distros and so many special cases. In order to support that ventoy must do some hook before boot. ) to find the source medium.īut with ventoy they will not find such medium because there is no such physical media and they don't know that they were booted from a virual disk. In normal case, the OS will search all the hardware storage media(CDROM/USB/HD. Most of the morden OS's kernels will use their driver to access hardware after boot, so the virtual disk will not be visible to them. In most case it works only in bootloader period. From the document you can see that ventoy will create a virtual disk from the iso file and boot it.īut the virtual disk is only on BIOS(Legacy or UEFI) level.
