I am a complete noob to this, but I downloaded iATKOS v7 and tried to burn it as an ISO. The problem is that I cannot boot from the CD. I tried using the CD on another computer, but i get "operating system not found."

My Laptop is a tx2000 from HP with a:
AMD 64x2
32-bit system
3 Gig memory

I downloaded several cd burners and made sure that the CD was supposed to be bootable. Any help would be great. Thanks in advance
