[CentOS] Installing Centos4.3 in VMWare on XP

Evening everyone,

   I'm trying to install Centos 4.3 in VMWare Workstation running
on Windows XP (my laptop). I downloaded the CD iso's to my
Linux box and burned them (I did them correctly since last time
I screwed them up). However, when I start the VM in VMWare,
it says the CD isn't bootable. Any ideas?

Thanks!

Jeff
