    I recently had the HDD replaced on my MBP by my Apple dealer and also had a RAM upgrade done at the same time.

    I had backed up the original drive using TM and the dealer did the same. When the computer was returned it had Lion installed from the previous Snow Leopard installation that came with the computer.

    I tried to partition the drive using boot camp but was unable to do so as I kept getting the following message "The startup disc must be formatted as a single Mac OS extended volume or already partitioned by Boot Camp Assistant for installing Windows". This same message came up in trying to create a partition using Disk Utility.

    I have since reformatted the HDD twice and re-installed Snow Leopard twice but still get the same message when trying to partition using Boot Camp or Disk Utility. The dealer is unable to help any further without me resorting to phone calls to the technical dept.

    Get Info shows the drive is formatted MAC OS Extended (Journaled).

    Can anyone assist with further checks I can do to find out the problem.

    Can you post a screenshot of the Disk Utility -> (Your disk) -> Partition tab.

    (Or open and post the output of the "diskutil list /dev/disk0" command.)
