[rg2000]

I just installed Jaguar, but the system won't boot up- it gets stuck on the grey screen with the little grey dial logo going around and round forever.
I think my hard drive may be too full- it only just allowed me to install Jaguar, and I have since read that I probably need an extra empty 500MB which I don't think I have. I would be happy to delete some stuff from my hd, only I can't figure out how. I can boot up from an install disk and use disk utilities, but nothing lets me access my hd.
Please help!

iBook, 20GB - was running 10.1.5 and still has 9 on it but I can't figure out how to boot up in either of these, as I can't alter my startup disk.

Thanks!

Hold down the option key when starting. That will allow you to select OS 9.

The option key trick only works when the respective systems reside on separate partitions. Same is true for the "D" key trick.

rg2000, if your iBook came with a system 9 CD and you have that available, boot from it. That ought to give you access to your internal drive's files. Of course, if you get this far, you can also select the OS 9 that's on the internal HD from the Startup Disk control panel and then boot from the internal drive, if you wish.

if you have another mac available you could start up your iBook in FireWire Target disk mode (by holding down the "t" key as you start up).

Then plug it in to another mac and it'll look just a like a hard drive - you should be free to delete whatever you need.
