I have not used Rufus but I think I have deduced from reading in context that it is a way of using a flash drive to create media.
No apologies ever needed as I have learned so much from all of you. I am 75 and have been quite ill so I am using the PC to keep me going in a positive way. I only began pc-ing a few years ago when things went south physically and this is a great way to feel productive again and to stay involved. My shrinking brain is coming alive. I learn from the good volunteers like yourself in forums. This is a great forum with extremely knowledgeable people. I am not much for social media but really enjoy learning various computer skills. I have folders into which I place information i have gathered that is either difficult or something one might forget.
I never learned the spreadsheet and at this point really do not want to so I make use of file and folders.
In the brief time I have been learning so much has developed; UEFI, USB 3, this new DISM measure etc.
One really has to stay on their toes.
Thanks once again for all of your help.
