How to boot Windows 11 from a Ventoy USB drive without installing it

¿How to boot Windows 11 from a Ventoy USB drive without installing it? If you enjoy tinkering with computers, you know that preparing a USB drive to install an operating system can be a real pain. We usually use either Microsoft's official tool or the classic Rufus, but both have the same problem: once you burn the ISO, the USB drive is locked to that system, and if you want to try another one, you have to erase everything and start from scratch.

This is where Ventoy comes in, a tool that's simply amazing because it's a game-changer. Basically, it turns your USB drive into a super flexible multi-start unit where you can drop as many ISOs as you want without having to flash anything each time, allowing you to choose which system to boot from a very simple menu.

What exactly is Ventoy and how is it different from Rufus?

Unlike traditional methods, Ventoy doesn't write the operating system image directly to the drive. Instead, it installs itself onto the USB drive to create a bootable structure. Once this is done, the USB drive behaves like a normal folder where you simply need to... drag and drop the ISO files from Windows 11, Ubuntu, or any other Linux distribution.

The big advantage is that you don't need to extract the contents of the ISO images; Ventoy reads them directly. Furthermore, while Rufus is great for deep customization, Ventoy shines for its ability to host multiple operating systems simultaneously, taking advantage of all the free space in your memory without restrictions.

Steps to prepare your multiboot USB

USB-C, Power Delivery and other standards

To begin, ideally you should use a USB drive of 32 GB or more. Keep in mind that current ISOs are quite large; for example, the 24H2 version of Windows 11 is around 5.5 GB, so this will determine how many systems you can carry with you.

Now comes the easy part: you just need to copy the Windows 11 ISO and any other ISO you want (like Chrome OS or a Linux distribution). The time it takes will depend on the speed of your USB port and the quality of the memory stick.

Boot Windows 11 and bypass restrictions

When you connect the memory stick to your computer and boot from the USB, you won't go directly into the installation; instead, you'll see the Ventoy menu. From there, select the program you want to start, and the deployment process will begin normally.

One very interesting detail is that Ventoy includes measurements for circumvent hardware requirements required by Microsoft. This means you can install the latest version of Windows 11 even if your computer doesn't strictly meet all the official requirements, which is a lifesaver for slightly older machines.
