Really simple problem while creating Windows XP

[codeMonkey112]

I am very new to Virtualbox and am creating a few of my first VM's. I created a Bactrack5 vm with no problems from an ISO, but I am having a really hard time creating a Windows XP VM. I downloaded a Windows XP .ISO from Microsoft's MSDNAA alliance from my school. I added the ISO to the VM under storage IDE Controler, but when I try to boot the VM it never starts windows and I get an error saying no bootable device was found. This seems like a really simple problem, but my searching for tutorials and youtube videos shows most people doing the same thing and it works.

I am also trying to do the same thing with a distribution of Linux from an .ISO and ran into the same problem. What is strange to me is that I did the same thing to create my Backtrack VM without any problems.

Any suggestions?

In the settings of your vm go to the system section. It the first option to boot from CD/DVD? Is it checked? If not make sure it is the first option and check the box. If it still fails, you ISO is probably corrupt.

Yes it is checked, I am beginning to think that both the ISO's I am using are corrupt. I re-downloaded one of them and it installed just fine.
