Hi there -- I just completed installing the 64-bit version of Release 5.5, and while the installation and initial configuration completed successfully, a full boot-up is never completed successfully. During the system boot-up sequence the list of services appears to complete, but then a blank blue screen appears, and while the mouse pointer is present, it does not respond to any input. I let the system stand, in the hope it would correct itself, for about half an hour, but the status did not change. I did the installation a second time to see if this was a freak occurrence. Unfortunately, after the second attempt was completed, the same issue occurred on the server. Prior to doing the installation, I confirmed the DVD and CD media were tested and found to be valid. When I did the installation, I went with the base install along with Server, Server GUI, and Virtualization support. The server hardware is a Dell R515 system with two 500 GB SAS drives that are hardware-based RAID1 that was completely optimized prior to the software install. Has anyone experienced this issue before, and has an idea as to what is going on, and how it can be corrected? Thanks.
