Boot Camp Assistant cannot partition

The other day at work I was given the task of setting up Windows 7 on a little MacBook. As per normal, we got Windows ordered in and the customer dropped off their laptop. However I had a couple of issues when performing the BootCamp.

I kicked the process off by running the assistant, aligning the partitions how I wanted them (and the customer agreed on), and set it to partition. However I got this error:

The disk cannot be partitioned because some files cannot be moved.
Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again

Some how I had a feeling that there might have been some errors on the drive that may have faulted this. So I run the Disk Utility on the drive from the CD and sure enough the drive had several error and were repaired.

I reattempted the partition, but same error. I spent a bit of time on the net finding a solution, and I did find one.

Solution:
Boot Mac OS X in Safe Mode, run the Boot Camp Assistant and partition the drive.

This worked for me, however the assistant didn’t recognise the Windows 7 DVD despite the DVD being genuine.

Solution:
After the partitioning, cancel the assistant and boot into normal mode. Continue the Boot Camp Assistant, and the setup will start to boot from the DVD.

Since it took me a while to find a solution on the net, I thought I would write up my experience to hopefully help someone else.
