What install CDs have you been using? The mirror door G4s are a fussy set, will only boot from OSX 10.2.2(approx and above) CDs, not OS9 CDs (even the dual boot models). If the machine is booting, check the machine can see the CD or DVDs ordinarily, if it isn't the optical drive has probably failed. The last few of those I've looked at I've had to put a new DVD drive in them as the laser had failed.
