What methods do other LQ users apply to create a Windows 10 bootable USB? Which software, and is there a sticky or how to? Using a desktop and legacy BIOS. It is for a dual boot system.

Personally I simply download the windows iso, then from my Linux desktop I use dd to write the iso to the USB device.

I have also used fedora media writer (on both linux and windows). I know that others have used etcher or rufus. Lots of choices available, and a very quick search for 'how to write an iso to usb' gives more than 19 million results.

Thanks, I don't yet have any windows going so I have to use Linux. Rufus doesn't work in Linux but I will look at the others.

On linux (most distros) the easiest way to write an iso to the usb device is to use dd.

A command such as
will easily copy the iso file to the usb device as an exact image.
- isofile.iso is the name of the image file to copy
- /dev/sdX is the name of the usb device. If it has partitions that auto-mount when inserted you must unmount those partitions before using dd to write to the device.
- bs is the block size you wish to use for reading/writing. I use 64M because I have plenty of memory and it speeds up the process dramatically instead of using the default 512 byte block size.

'man dd' will give you all the info on how to use the dd command if you want to understand it better.

I agree. The OP has seemed reluctant to try using 'dd' and when he opened this I wanted to stress the easy way, not the alternates.

Yes I prefer a GUI to code. So I used Ventoy and it went well.
