Boot camp assistant not giving option to boot from windows partition drive

Question

Hi, I am a recent convert to Mac OS (10.6.8) on my three year old Macbook. I have been using windows on boot camp since the beginning and have just shifted to OS as the windows was taking too much space and running quite slow (not to mention the viruses accumulating!). I am getting better at it now, only Excel being problematic adjusting to with the different and less convenient keyboard shortcut keys!
Whilst moving over to MacOS, I changed around the disk partitions using disk utility to free up and utilize some unused space. My Boot camp partition still exists untouched, but the boot camp assistant is not giving me the option to restart the computer using the C: drive (and enter windows). I also have saved data on windows that i want to transfer over to MacOS. Any suggestions please? all help/comments will be much appreciated! Thanks.
