    Don't use grub myself - I believe it points to hd and partition number.

    If you remove a partition - you would need to alter that to match

    GRUB chainloads Windows bootsectors. In my case, that would be (hd0,3), or my C: drive. And the 100MB partition, called "DELLUTILITY", has no Windows boot files. It has some DOS ones, and what are (presumably) some Dell Utilities.

    Yes, so if you get rid of the 100mb, you would need to change it to (hd0,2) I assume.

    He's got 2 partitions to the left of C: that need removed, that will change this correct?

    Does he want to get rid of both of them? - too lazy to look back- whatever, Marionumber knows what to do already. Looks like he's using grub2.

    I think he does, it would serve him better if he wiped and recovered both partitions into C:

    Okay, I'll wipe it. And in case of emergency, I got a Windows 7 repair disc and Ubuntu LiveCD.

    I am puzzled. In your disk management snip I see the Recovery Partition as active partition. So the bootmgr must have somehow ended up there. I do not understand the Grub deal. The MBR should be pointing to the recovery partition.
    It's the MBR boot code which determines what to do with the partition flagged active in the partition table.
    I don't know much about Grub but I believe it can change the MBR code. So normal MBR booting may not apply.

    Edit: I would not just delete the recovery partition without seeing what is inside it. Partition Wizard mini tool allows you to easily explore the recovery partition.
    When you say "I'm using Grub2 in the MBR" what do you actually mean?

    Dell routinely use the Recovery partition as active, system.

    No need to wipe anything - just delete the partitions before incorporating the unallocated space into your windows partition.

    You would need a 3rd party partitioner for that - one made for windows.

    If he's going to recover 2 partitions to the left of C: into C: he's going to need a 3rd party SW, the best is the Partition Wizard boot disk and a wipe will only take a few minutes on factory recovery partitions and there's been instances of disk management not allowing a "Recovery" partition marked as active to be simply deleted, it had to be wiped first, he might as well save the trouble and just do the wipes.
