Move very quickly to the phone and call Apple. This thing should still be under warranty, first year, and the sooner you inform Apple the better. Once you have contacted Apple, get them to give you a Case number. This number proves that you had the problem before the end of the warranty. After trouble shooting with you, they will probably ask for the iBook to be sent to them for repair. (I believe that iBooks all go to one place for repair)
I think you are looking at some form of hardware failure. Especially if this happened directly after a "Format and Install" The fact that the installer is unable to find the HD is indicative of an HD failure. Good call on the backup!
Talk with Apple
ok, so i have had an ibook since March and everything has been just perfect. i have kept all my software up to date and use the computer for all the basic uses; photos, music, word docs, and internet.
Last week the ibook just began acting up so I decided I would need to back it up just in case anything went sour. After a day or two of the ibook simply not working properly I decided it was time to reformat and start over (i did this after of course trying all things like repairing the permissions...).
I reinstalled Mac OS X 10.3 and did all the updates. I did not even restore any of my information yet! I restarted my Mac after and update and blam! nothing I get a question mark. after resetting it a few times, now I get the everlasting spinning apple screen. I tried using the install disk to try another reformat, and it boots to the installer fine, but now the installer is unable to find my hard drive!!!!
Anyone have an problems like this? Anyone havean advice?
I have a iBook G4 800 MHZ 384 megs of ram, 30 gig hard drive.
