Hello Bob, You'll need to boot from your install DVD to format or partition the start-up drive. Dean Danis 519-494-8639 90 Caprice Cr.

Problem now in Disk Utility is to select a disk (drive) where "Partition" shows and Volume Scheme and Volume Information boxes are not greyed out. After sitting awhile another entry appears below Macintosh HD and my optical drive: Bob McDaniel's MacBook Pro, and indented below, time capsule backups. I sure don't want to erase the backups! It also says that the currently selected disk (200.05 GB FUJITSU MMY 22) is the start-up disk and it cannot be erased. BTW when I select "Macintosh HD" the "Partition" button does not appear.Bob On 2010-06-28, at 7:16 AM, Dean Danis wrote:Once you partition a drive ALL data will be lost on it. Disk Utility will format the drive for you once partitioned. Review your time machine backup to make sure that important data is backed up before proceeding. _________________________________________________________________ Learn more ways to connect with your buddies now http://go.microsoft.com/?linkid=9734388
