Susan, how old is your laptop? If it is newer and totally capable of running Windows 11, then take your laptop to someone who really knows what they are doing. For peace of mind, that is what you should do.
I'm glad you backed out on that one solution. As you can clearly see, this leading you down the road to hell which is why I won't do any of that.
If your laptop is older and questionable about how much Ram you have and everything you need in order to run Windows 11 properly, I would buy a new one with Windows 11 installed. Save all of your important files and photos and documents to the cloud (one drive, google drive or USB drives). Once you have the new laptop working, just install all of your files you need or want.
Getting old and not understanding all this computer stuff is enough to make you want to tear your head off. Gosh, we have so many other things to worry about right?
I'd like to send you a personal message or exchange emails privately, but I don't know how to do that. I'd love to stay in touch with you as we go down this road together. Sympathy loves company. :)
