The problem is that the Hyper-V management console is not responding fast enough for us to "catch" the F8 option. We open the console, start the VM, click in the console to grab control. But the console just says, "Starting (and some misc info)..." But it does not show the usual BIOS boot info. Eventually it displays real boot up activity, but by then, it's well past the point where we could have pressed F8.
The guest VM is a 2011 SBS system that won't boot and we want to try to get started in safe mode. It would also be the DC, DNS, etc. for the network. Wer'e thinking it's unvailability to the Hyper-V may be causing the slow response and access to the console. Any ideas? Suggestions?
