dual booting

Hi everyone. I would like to have Windows 7 and Windows Vista on the same hard drive. Is that possible? I have been reading the tutorial, but I cannot make another primary partition or make a logical drive on my hard drive. Also, can you use a 32 bit operating system of Vista on a 64 bit Windows 7? There are programs that will work on windows Vista, but will not operate on Window 7. I was thinking of installing a second HD, but I do not have an opening for it. I would appreciate any help that is given to me. I am attaching a picture of my disk management for reference. Thank you. deanie44

You will need to make Partitions 4,5,6. in to one partition.

Any program that will run in Vista should also be able to run in Win7, if necessary using Compatibility Mode.

If you miss it that badly you can install Vista to the Logical free space using Bare foot's steps.

You can also gather the Unallocated space at the right end of the HD into the Media Center partition when you're ready by rightclicking it in Disk Mgmt to Delete Volume (making it Logical Free Space) then Extend Media Center partition using tutorial posted by Shadowjk.

Thanks you fellows for helping me, but I decided not to install Vista. What was I thinking. I get bored every once in a while and feel the need to experiment. Sorry for the inconvenience I may have caused anyone. Thanks deanie44
