I tried (several times) installing CentOS-5.6 from a hard disk, and each time it failed after installing all the rpms, with the warning "The installation has tried to mount image #2, but cannot find it on the hard drive."
Strange, I install it from the DVD.iso to VMWare images a couple times a month, haven't seen that issue.
Once a new release gets approved for production, I copy the contents of the DVD.iso to our PXE Boot server, and install production machines from there.
(FWIW, I have not installed in onto real hardware, from a real DVD, in a couple years now..)
Are you sure your DVD matches the checksums?
Yes: md5sum -c md5sum.txt.asc CentOS-5.6-x86_64-bin-DVD-1of2.iso: OK
As I said, I installed CentOS-5.6 by http without problem. I've also installed it by netinstall and on a USB stick. But I haven't been able to install it from the hard disk, as I said. I'm pretty sure it is a bug in the installer program.
