	Mac: Dual G5 Problem: Can't upgrade from Panther to Tiger Situation: I run the Tiger install, it stops towards the end saying there is a problem with the software and restart. I do x 15-16. So, I decide to lobotomize the thing. Not to worry - all my data is backed up. Same thing. So, I run Disk Utility (on Tiger CD) and run the Repair and it says the disc won't unmount, so it can't repair. So now, I have a lobotmized G5, the only OS that's working is from the CD. Any thoughts/suggestions? Thanks.
