Greetings ! I'm trying to install windows tonight on my MBP. When creating a partition for Windows XP, I choose 10gigs for Windows and the rest for OSX. I click "Partition" then aftert it crunches some numbers this shows up: You're startup disk cannot be partitioned because verificaiton failed. Start up your Mac from a Mac OSX Install Disc and use Disk Utility to repair your start up disk. Hrm form what I can gather I needed to start up my Mac OSZ with the install disk in, go to disk utilites then press repair disk on my HD or the Install disk. Although both are shaded out where Repair Disk is. What do i need to do?
