Sounds like the school of Hard Knocks.
It's how we learn best.
I've trashed this machine many times.
I got a lot of practice rebuilding it the hard way.
Then I discovered backups.
That allowed me to rebuild the machine the easy way.
As time went on, and I got a little smarter, I found I
didn't trash the machine very often.
I still make backups but they just sit in a draw without
much to do.
I've only had this thing for about a year but it took me a long time to figure out that sometimes "ENTER" means "SELF DESTRUCT!!!!!!!!!!!
Don't ever go into the operating programs thinking you're going to delete something you don't need or whatever.Stay out of any program until you know exactly what it does or how it's tied to other things.
I've been to the shop to many times.
