I was installing OSX 10.5 (from 10.4.??) when my computer froze up after 4% completion. I attempted the install several more times with the same result so I tried to reboot using the 10.4.?? as my start up disk. The computer chimes, I get a gray screen for a couple of second and then I get the following: localhost:/ root# CSRHIDTransitionDriver::stop IOBluetoothHCIController::start Idle Timer Stopped If I hit "return" I then get: localhost:/ root# I've sapped the pram (hoping it would be that easy) but still the same thing. What I believe has happened is that my harddrive got renamed during the 4% install and now that I'm trying to boot up using it, the computer can't find it (just my guess). I ran the fsk (or whatever the line code is to check my harddrive) and everything came back "OK". So I'm at a loss. Can any one please help? Thanks!
