I’m currently in the process of upgrading a standalone Server 2012 machine running Hyper-V to Server 2012 R2.
Due to resource constraints, I’m performing an in-place upgrade, despite this server residing 800km away from me. Thank goodness for iDRAC Enterprise.
However, during this process, during the “Getting Devices Ready” section I received a Blue Screen Of Death, with the error message:
After it hit this BSOD twice, the upgrade process failed out and reverted back to Server 2012. I was unable to find a log file of what occurred in any more detail, and was worried that I would be stuck on Server 2012.
Thankfully, I discovered a log file on the iDRAC with the following message:
A bus fatal error was detected on a component at slot 1.
This triggered my memory, and I recalled that we have a USB3 PCI-E card installed for pre-seeding an external drive with backup info.
I used the BIOS setup (Integrated Devices > Slot Disablement) to disable Slot 1, and then retried the upgrade with fingers crossed.
