This question was asked some time ago.https://www.computerhope.com/forum/index.php?topic=63014.0The answer was to get a CD Drive.
However, what I am trying right now with what I have will not work.m The portable CD-drive I had has long ago failed and is in the junk pile. And older drive I had have also gone bad.
I do have PCs with drives, but trying to remove a drive is not feasible. So, here is the same question again.
How do you put the Windows XP setup on a USB stick?
And make it boot?
EDIT: Now I see I asked before.
Sorry, I am having a senior moment.
