ibook crashed

try holding down option when it boots, it should show any valid system folders. Post back if nothing comes up. Also, what model ibook is this? clamshell, firewire clamshell, dualusb, g4?

Hello. Thanks for your answer. I've tried the option-trick, and the ibook showed two arrows to click on; one turning and one to the right. When I used the arrow pointing to the right, nothing happens. Strange, because this arrow had the extra edge showing. The turning arrow makes the ibook try something (I guess it tries to boot again). But it also did not take it any further. Any ideas?
The ibook is just a simple ibook blueberry (I guess clamshell for there is no firewire port) and runs MacOS 8.6 (it has got an Ethernet-port and I know the ethernet-ID of the ibook, if that is of any help). I have also an G4 (desktop, MacOS 10.2.3) and 2 old models: Power Macintosh 8200/120 (MacOS 7.0.1) and an Apple Classic (just for the kids; bought it for €5,- so they don't use my G4)

try DiskWarrior 3.0.3.... saves almost everything. costs a bout a hundred bucks... or less if you know where torr look for it.

as you mentioned, using the option button on start up only gives you a screen with two buttons, one turning and one to the right. normally it would show you bootable volumes inbetween of the two buttons. in your case, no bootable volumes (from which you could start the operating system) could be found.

like evilrobot stated, try to fix that problem with your hard disk (either with disk warrior or norton utils). if there is no hardware fault causing that problem, your machine should work afterwards without problems...

regards, chris

btw: the "turning" button makes the iBook search for bootable volumes again. if you selected a boot device by clicking on it, you can start from that drive using the "to the right" button...
