OS X has disappeared!

A friend of mine bought a new I-Book a few months ago and chose to have 9.2 on it, since that's the OS she was familiar with (also has a G4 desktop with 9.2).

Recently she decided to upgrade to OS X (10.2) using the installation CD that was provided to her at the time of her purchase of the I-Book.

I ran that upgrade for her and it seemed to go ok, except for some weird behavior involving "opening the classic operating system" whenever she opened old word documents.

Today she called me and said her OS X is completely gone!  When she boots up her I-Book, she's back on 9.2.

How is this possible?

OS X and OS 9.2 exist side by side on the HD. She's only booted into OS 9. Tell her to open the startup disk control panel and select the OS X system folder. Also, she SHOULD be using 10.2.4 and 9.2.2. Make sure you apply those updates.

The weird behavior she was experiencing when launching classic was probably just the notice that components were being added to the 9.2 system folder for classic compatibility.

I mis-typed the first time.

Should be 10.1 not 10.2

The only CD that came with her Ibook is 10.1.

Will that make a difference?
Not really but she should be running 10.2.4. 10.1 is quite old.
