Can we assign D drive first to Hard Disk

Hy,
Is it possible to assign D drive for hard disk without giving C drive first Means I format my Hard Disk and want to create single partion naming D drive (means i want to assign D to my first partion)so there is only D drive in disk no c drive in hard disk . Finally when i open my PC it shows A for 3.5 inch floppy and D for Hard disk . Assume no CD drive there.Is it Possible?? How can we do it

Possible in Windows XP, using disk management (right click my computer and manage).

 

The primary partition will always be the C drive.
You cannot assign a D drive to a single drive which can also be your primary partition.

 

You can do it in Windows XP! Even if u have just one partition!! Just try it out!

 

Thanks
I will try in XP

 

u can set the D:\ as active so that os boots from that
