Your ethics and choice here.
But your story is much like what happens when I own a car, but lose the keys. I still have to pay a small fee to get back in. And I get new keys as well.
Since they have the OS CD, the only remaining issue is this.
How many times I find a PC owner that a friend loaded the OS and now they need the OS CD. We find the 2 out of three restore CDs, just like before. Since I can't part with free copies of Windows 98, I have to walk away and wait for CDs to show up.
Your choice on what you'll do, but it's all in the lesson plan about backup and keeping track of your car keys.
Okay, I am helping a friend's 13 year old daughter, who (despite my advice) Kazaa-ed her computer and now... well, it doesn't work.
I tod her it best to reformat, and I put in an eMachine Recovery disk (one of two) and needless to say, she doesn't know where disk two of two is. It ran something called Norton Ghost, and asked for disk two.
Okay, so now she has an large paperweight.
Her computer can't boot and I don't know what to do.
Can I reformat using my old Win 98 from my Aptiva?
Is this ethical? I mean she is downgrading. She owns a Microsoft OS, but just can't find the appropriate disk.
