Get a genuine Windows Server 2003 CD. Why would you want Windows Server 2003 anyway?
Haha, it IS a genuine disk, I bought it a few years ago.
I'm using it for a home server for all the computers in my house. With 9 computers in the house constantly having flash drives being thrown around to print stuff, I wanna make a legit server that everybody can use as a vps to store w.e they want.
I WOULD use 2008 but I don't have the money to fork up right now, and I've had a copy of 2003 since about 2006 haha. So yeahh..
If it's genuine, you should be able to boot from it. That's the only way to install Windows Server 2003.
