[rizshinigami]

I just installed windows 7 x64 on drive B (boot,crash dump and primary partition), then i decided to completely remove vista x64 on drive c(system,page file,active and primary partition) and make that as another data storage.But i cant delete or format the drive C.How can i do it?And i want the windows 7x64 to be mark as drive C.Can you help me?They're both on same single hardisk.

Have you tried Disk Management?

Start->Run->Type: "compmgmt.msc" (without the quotes)->Press Enter->Expand "Storage" in left pane->Click "Disk Management"

Yes i've already tried that but it didnt have delete or format option on drive C. maybe it couldnt be delete because its contain the primary system(?).I coudlnt fresh install windows 7 on drive c because my dvd is corrupted so i had to install vista x64( dont have service pack) first then mount the iso to install win 7 on another partition which result vista x64 as drive C.

As far as I'm aware Windows is mostly used as the C drive, therefore it is unable to delete itself so to speak, I'd recommend using your Windows installation disc and reinstalling the OS of your choice onto the known C drive. and whilst using the Windows disc delete/format the other drives/partitions to what you want/need.

EDIT: just read your Win7 disc is screwed... how about cloning your Win7 installtion to the current C drive? However I don't think this will be as effective in the long term due to your drive setup and also will no doubt leave the Vista files.

you cant change the drive letter of the system drive in windows.
