To create an empty Hard Drive image do:
qemu-img create <filename> <size>
for example:
qemu-img create windows.img 2G
You can also use the preferred ("qcow") image format by doing:
qemu-img create -f qcow windows.img 2G
That gives you the ability to save snapshots, encrypt the image, etc.
Now we'll use this image:
qemu -hda windows.img -cdrom /dev/cdrom -m 256 -boot d
That says:
"-hda windows.img" == Use the file windows.img for the first disk
"-cdrom /dev/cdrom" == Use /dev/cdrom for the CDROM
"-m 256" == Use 256MB of memory
"-boot d" == "Boot off of drive 'd', aka the cdrom"
