I'm attempting to install Windows 11 using the `autounattend.xml` method to make the process smoother. Here's my step-by-step process so far:
1. I downloaded the official Windows installation media ISO.
2. I created an `autounattend.xml` file using a generator.
3. I used Rufus to make a bootable USB drive from the ISO.
4. Once Rufus finished, I placed the `autounattend.xml` at the root of the USB drive.
5. I then started the installation on my target laptop.
However, I ran into some snags because I'm not very experienced with this. I thought it would be easy to just generate a new `autounattend.xml` if I made a mistake. But when I tried to edit the USB, I faced two problems:
- The USB was no longer accessible for edits since it mounted as a DVD drive and didn't have enough space for the new file.
- The `autounattend.xml` file I had already placed on the USB seemed to be missing.
Now I have to redo the Rufus process from the beginning, which takes over 30 minutes. I'm sure there's a better way to handle this, right? Also, I'm blocked by some IRST driver issues, where my SSD isn't showing up for installation, and the drivers I've downloaded aren't recognized. Any advice on how to resolve this would be really appreciated!

Avoid using Rufus and `autounattend.xml` together; they can conflict and create problems. I prefer `autounattend.xml` because it offers more customizability but it does require a bit of learning. Check out this generator link I’ve used before—it’s very helpful!
It’s possible that your `autounattend.xml` is messing with the partitioning of your USB. Try to keep that section untouched. You may want to allow Windows setup to handle the disk partitioning. It's usually a smoother process!
If you want to skip Rufus altogether, using the Media Creation Tool (MCT) can be a good alternative. Just remember to drop your `autounattend.xml` in the root directory after creating the USB. That way, you won’t need to redo everything!
You might want to try using Ventoy instead of Rufus. It makes handling multiple ISO files easier and doesn't mess with the USB like Rufus does. Plus, for things like network installs, Ventoy really shines!
Thanks, Ventoy seems like the solution I need! I’m still struggling with those IRST drivers though.
Rufus tends to create two partitions, which could be why you’re having trouble accessing your USB. Are you sure you're trying to edit the right partition? Make sure you’re viewing the main one!

I see what you mean about the Media Creation Tool, but it still took a lot of time to prepare the USB. My main goal is to update `autounattend.xml` easily without repeating the whole process.
