So, how does it actually work?

  In the common case: Boot Ventoy application via GRUB/EFI Ventoy EFI application scans the same drive it booted from with a vfat driver for disk images. Ventoy then creates chainload grub commands for every image it finds. You are presented a list of boot options, just like a normal grub boot. Selecting an option chainloads a boot from that disk image. There's devil in the details of course, but largely that's how it's working.

  There is a "How Ventoy works" section. First part is listing there open source dependencies https://www.ventoy.net/en/doc_disk_layout.html https://www.ventoy.net/en/doc_disk_layout.html https://www.ventoy.net/en/doc_disk_layout_gpt.html https://www.ventoy.net/en/doc_disk_layout_gpt.html https://www.ventoy.net/en/doc_mbr_vs_gpt.html https://www.ventoy.net/en/doc_mbr_vs_gpt.html ...

  If you mean, technically, I can't help you. But for users: You install Ventoy on your USB drive, and then you can drop ISO files in a folder. On startup, Ventoy opens and you can choose the ISO to boot. This means you just have one bootable USB, and no more using tools to create bootable usb drives.

  See https://en.wikipedia.org/wiki/Ventoy#How_does_Ventoy_work https://en.wikipedia.org/wiki/Ventoy#How_does_Ventoy_work, TLDR when you pick an ISO, it sets up a virtual device which emulates a regular bootable device, pointing to the contents in the ISO.

    This section of the wikipedia article is entirely uncited, and reads vaguely like LLM output. Ventoy is not a hypervisor (afaik), so how does it present an emulated device to a chainloaded OS? This is the edit that introduced that section, originally titled "How does Ventroy works" https://en.wikipedia.org/w/index.php?title=Ventoy&diff=1224769425&oldid=1224767737 https://en.wikipedia.org/w/index.php?title=Ventoy&diff=12247...
