I've recently started using Ventoy for creating installation media on a single USB drive, which has been a game-changer for me. My previous attempts at using cheap USB drives always ended with them failing after a few months. I find Ventoy to be quite magical, but I'm not looking for specific technical details. Instead, I would love a high-level, abstract explanation of how Ventoy actually works and what makes it so effective for managing bootable USB drives.

Basically, Ventoy acts like a bootloader, similar to what you see when installing Ubuntu. Instead of just booting one operating system, it allows you to boot different operating systems from a single USB drive. It simplifies the process significantly, giving you more options at boot time.
Creating a bootable USB with Ventoy involves setting up a 32MB partition for Linux on the drive, which allows you to mount ISO or IMG files and boot from them. There's really no magic here; just a clever implementation. And if you’re looking for a long-lasting flash drive, consider the Sonizoon SLC drives—they're a bit pricier, but they’re built to last.
The key behind Ventoy is that it uses ISO images, which are like snapshots of filesystems. These can be 'mounted' and accessed like regular files, letting you boot from them. While Ventoy has additional features, fundamentally it's built around using GRUB to manage those ISOs. It's essentially a smart way to handle multiple OS boot options without constant formatting.
Hey, booting an OS is a layered process. It starts with the BIOS that looks for storage devices, then hands off to a bootloader. Ventoy fits in here by managing the boot loads from your USB. You can even have multiple boot loaders working together. It's all pretty flexible.

Exactly! It makes the process so much easier compared to the old ways. Just drop your ISO files onto the USB, and you're set.
