Thanks for the links!!! I find Apple's support site very confusing !!!

The first 3 options don't work, the machine can't boot into Safe Mode

I have a USB PC keyboard, and I can't get the last option to work as I don't have an Option key to press and hold, any ideas? (my Apple KB is bluetooth and doesn't seem to be working before bootup).

Another problem is the disk in the drive, how do I get it out? How to I tell the mac to boot from the CD at start up? That could be one solution, it's the original recovery CD that came with the machine this's stuck.

Cheers

Cris.
