After finishing the preinstallation I got the following error message:
Cisco Unified CallManager 220.127.116.1100-2
The installation has encountered a unrecoverable
internal error. For further assistance report the
following information to your support provider.
install PostInstall 18.104.22.16800-2 22.214.171.12400-2
/common/log/install/install.log" exited with errors (1)
The system will now halt.
When I reboot the system I have the following error:
"INSTALLATION FAILED - restart installation to recover from failure"
And then, if I reboot the system with the Install DVD or Recovery DVD it stops working (no keyboard input and no video output).
What can I do?
