Cant format a Primary partition.

I really should know whats going on but i cant think straight.
I want to format my D: drive to clear some space. Thing is my D: used to be my C: drive under XP when i was dual booting so its showing as an active primary partition and W7 wont let me format it.
Ive tried deleting everything but some things are refusing to go (like the file boot which i assume is to do with dual booting)
Can someone please help.
Im not really as stupid as i seem
Thanks.

Dave.

couple of options

1. Go the the web site of manufacturer of your hard drive and get their
free disk utility. Usually they have a program on there to format
your hard drive.

2. Download Gparted boot cd and boot that and format your drive.

thanks for the options.
I THINK my problem is the boot manager for my PC is on this drive, even though im booting from my C: drive.
Im going to try and move the Bootmanager to my C: drive and then see if i can format in the usual way.

I've no experience of moving the BOOTMGR and had a problem with this earlier, but you can simply pop in your Win7 DVD/USB and after selecting a language, click on Repair instead of Install, and you should get the option to check your boot configuration; Win7 should do the rest for you in a matter of seconds.

Thanks. ive had to do that twice tonight, each time the repair puts bootmanager back on the D: drive.

Im going to give it a rest for now.

Unplug the D: drive whilst you rebuild the MBR (assuming it is a physical drive and not a partition)
And/or look in Disk Management and make sure the right drive/partition/s is/are set to active.

Also, I reccommend taking a look at the tutorials on this site (if you haven't already) -- can't hurt, can it?

There is a free partitioning program that will allow you to boot into it, recreate the partition/delete/format it outside of Windows.

You might also want to run a disk check though. Sometimes when you move the Boot config it must be rebuilt (the second link shows you how to do it)

Thanks for the help guys.
My main worry now is the bootmanager. I can restore it but cant seem to move it so the suggestions above could be the answer.
Jeff, ill try your first as it a bit of a pain to get my PC open to disconnect the drive.
Are you saying that if i delete the partition the bootmanager will reflect this and W7 will create a new one on my C: drive?
