George talked a bit in the meeting today about booting from a USB Recovery Drive. I recently stumbled across an article that covers how to boot from a recovery drive. It’s especially valuable for its coverage of handling the process for newer computers that use UEFI. That’s something that (fortunately) I have no experience with.
The article — BIOS/UEFI Setup Guide: Boot from a CD, DVD, USB Drive or SD Card — explains things clearly, and provides important information on booting computers from different makers. You might want to look it over before the meeting next week.
An item that points to that article is buried in my (updated) collection of articles — Troubleshoot Windows 10 using its own tools… And more… if you are interested in more context.
