Microsoft's installation-media instructions

ReinstallOS · updated 10 November 2026

Why the vendor's support article beats a tutorial screenshot when the prompts change, and what the article actually covers.

Official source Create installation media for Windows support.microsoft.com

This site links to the vendor's own page and hosts no files. Check the hostname before you download anything.

Alongside the download page, Microsoft publishes a support article describing how to create Windows installation media: what the tool needs, what it does, and the choices it presents. It is not a narrative tutorial and it does not contain screenshots of every screen. It is nevertheless the best source for the exact wording of the prompts, because the vendor updates it when the tool changes.

This page explains how to use that article alongside a walkthrough, and which parts people routinely skip.

What the article settles

Questions of current behaviour belong here: the size of USB stick required, whether the tool can produce an ISO as well as a bootable stick, what language and edition selections mean, and the fact that everything on the chosen drive will be erased. Those details have changed between releases, which is why a screenshot from a three-year-old tutorial is a poor authority.

The article also states the licensing position plainly. Creating media is not the same as acquiring a licence, and the tool does not bypass activation. If a guide implies otherwise, it is describing a different, unofficial tool.

  • Current requirements for the USB stick and the tool.
  • The exact names of the choices the tool presents.
  • Whether an ISO output is available and how it differs from a written stick.
  • The relationship between installation media and a licence.

What it does not cover

It does not tell you which partitions to delete, how to enter your particular machine's boot menu, or how to recover a BitLocker key. Those are hardware-specific or destructive decisions, and this site's guides handle them separately so they can be read slowly.

It also does not cover third-party USB writers. If you chose the direct ISO route, the writer's own documentation is the next place to look — but the image being written should still have come from Microsoft.

Use two sources, in the right order

Vendor documentation for what the tool says and does; a walkthrough for the sequence of decisions around it. When the two disagree, the vendor wins.

The paragraph people skip

The article states that creating installation media erases the USB drive. That sentence is responsible for more lost files than any other line in the process, because the tool presents a list of drives by letter and size and it is easy to be confident about the wrong one. Before running it, disconnect external disks you do not need and check the drive letter in File Explorer.

The same article is where Microsoft describes what to do if the media does not work as expected. Rewriting the stick from a fresh download is a cheaper first response than changing firmware security settings.

A practical reading order

Read the vendor article once before downloading anything, then keep it open on a second device while you work. Follow the walkthrough for the actual order of operations, and return to the article whenever a prompt's wording does not match what you expected.

If the wording has changed, trust the article and adapt; do not hunt for an older version of the tool that matches the screenshot. An installer that is current is part of the point of doing this at all.

Mistakes to avoid

  • Following a screenshot-heavy tutorial from an older release when the vendor's own article describes different prompts.
  • Skipping the note that the USB drive will be erased, and picking the wrong drive letter.
  • Expecting the article to explain partition deletion or model-specific boot keys.
  • Assuming creating media also grants a licence.
  • Changing Secure Boot or enabling legacy boot because a rewritten stick was not tried first.

Questions people ask

Should I use the article instead of a walkthrough?

Use both. The article is authoritative about the tool; a walkthrough gives the sequence and the destructive decisions their own space.

The prompt wording on my screen is different. What now?

Follow the vendor's current wording. Tools change between releases; older screenshots are not a reliable guide.

Can the tool make an ISO as well as a USB stick?

The vendor article describes the available outputs for the current tool. If you need an ISO for a VM, the direct ISO option on the download page is the other route.

Does this page host the tool itself?

No. This site hosts no binaries. The link goes to Microsoft's own support page, where the current instructions and download live.
