So your daughter is less computer capable than you.
You cannot part with your old machine because it has been Mike-afied to the point it suits you perfectly and you can't part with it.

OK
Let's go back to Win 11 and let me try again to communicate the frustrating situation. We got some good news yesterday -- changeover is pushed back over 2 years.
Microsoft is killing off Win 10
fairly soon. At the Biden administration's pointed request, MS has moved back the changeover deadline from this fall to fall of 2024. Doing this MS forced changeover right now during a period of severe chip shortage is "not Biden approved activity" as it will affect the entire economy and exacerbate the effects of the chip shortage.
You will have to buy a new Windows 11 machine soon enough. MS says so. Spendy spendy spendy lots of $$$$$ on whatever MS wants you to buy.
Or, stay on Win 10 whenever it becomes unsafe ---- eventually to be eaten by some transmitted thing over the internet. Some on this list will take this route, some will have it work out OK, some will die horribly.
Or, jump ship to Linux ........ this requires a willingness to learn.
I had a boss once named Karl, he was like you, not very good with computers.
He would take his machine to Best Buy and they would tell him why they couldn't fix it.
Karl bought a new computer at Best Buy every 1-2 years .......
Karl was caught in the Wintel trap, and he knew it. Resented it, but he knew it had him half swallowed all the time.
Karl would bring his computer to work and I would fix it (generally simple things).
He'd take it home and break it again futzing around on the internet downloading stuff and installing it himself.
Karl bought a lot of computers.
My wife does this with her phone. Downloads new apps and breaks everything trying to install them while reading on the internet and futzing around with the settings.
KISS Keep it Simple If it works don't futz with it.
Still, I buy a lot of phones for her because she uses them up pretty quickly.
People like Karl need to use Chromebooks because they cost less to replace.
Mike, dig out your best newest old machine and charge it.
Does the DVD drive work? Does it recognize a DVD once inserted? Notice I said DVD, not CD.
Stick the Mint DVD in it and turn the laptop off, then
restart the machine with the DVD sitting in the closed DVD drive and then let it set for 15-20 minutes while it oh so slowly starts itself up.
Did Mint load up?
Loading an OS from a DVD is slow stuff, but once loaded off the DVD it can be installed on your hard drive where it will run much quicker.
