    Just installed windows 7 and everything is working perfectly... BUT. I had my vista on D: drive, now I have 7 on C: drive but windows vista is still at D:, anyone know how to uninstall it? Tried formatting, no effect. (yes, tried cmd->run as administrator->format D:, didn't work either), so any help ?

    Why not just use disk manager and delete the partition that holds Vista? I don't understand why you can't format. Are you sure you are booting to 7? :)

    Are your C: and D: drives actually 2 physically separate drives or are they just separate Partitions on one drive? I would go to Computer Management - Disk Management and delete the partition as suggested either way, but remember you will have to repartition that drive or partition for the space to be available for use after you are done.

    The probable reason he can't format the Vista partition is that when Win 7 was installed, it put it's boot files on the Vista partition. That's the way Windows dual boots work and why it's not straight forward how to get rid of the original OS.

    That's so obvious now that you mention it, DVOM, but I sure didn't think of it when I first saw the thread. :) I think one solution is to make the Windows 7 partition the Active partition, delete the other one, then boot to the Windows 7 DVD and repair the boot. If Disk Management won't/can't do it, EASEUS Partition Master can. As always when messing with partitions, be prepared to start with a fresh install.

    Do you have the Windows 7 Disk with you?
    If yes, the process would be less complicated than using the EASEUS Partition Master
