Which guest OS did you select for the VM, and which virtual disk controller is used. It looks like the Windows installation image doesn't have the required drive included, and you may need to provide the driver during the installation (using the "F6" key IIRC).
Please attach the the VM's vmware.log to a reply post.
Update. Just booted the machine again, now it's complaining about missing NTLDR.

You can't have the virtual floppy disk connected at boot, otherwise the PC tries to boot from the A drive. And the device driver for the virtual disk adapter floppy isn't bootable.
