[ubuntu] windows 7 on ubuntu

simple questions to everyone who knows what to do...
i'm new in here so i don't ...

can someone tell me how to install windows 7 on
ubuntu-12.04.1-desktop-amd64

the easy way...
vmware?

-----------------------------------------------------------
what i'm really up to is install that ubuntu on freshly
formated HDD 250GB
then install windows 7 so i can (i think) have plug-n-play
ubuntu with windows 7 on it...

can i do that??

thanks in advance
Dan
