comment Stuck at grub prompt after a default CentOS 6 installation
I'm familiar with testing memory, hard drive, mobo, etc -- but it's quite time-consuming and I think it's unlikely that two sets of relatively new equipment (differing memory and HDDs) could start having the exact same problem at the exact same time. I had previously installed CentOS on these servers a couple times within the past ~4 months.

An interesting finding... I attempted to re-install with CentOS 5 for good measure and I received this error about corrupt media during the installation: pasteboard.co/28oIkauh.png -- I hit retry, the install continued without error, I rebooted and the CentOS 5 booted up normally. I never received an error like that with CentOS 6 net-install -- despite re-installing at least a dozen times. Maybe the CentOS 6 net-install isn't catching failures like CentOS 5 does -- do you think that could be the root cause?

I get the same result as before when I run grub-install /dev/sda without removing device.map. I rebooted, grub prompt is gone, but in its place is an Error 21 message -- selected disk does not exist. I've experienced this error on two completely different sets of hardware (identical server configuration though). I suppose a network issue could be to blame, but I've repeated the CentOS install so many times that I doubt that's the issue. Ubuntu net-install works fine.

I'm loading up the rescue shell to try that now, but could you explain how that will work? As I understand it, the contents of my device.map are fine.
