Can you start Hyper-V Guest (Win 2008) in Safe Mode WITHOUT F8?

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?

Much like a physical system, you can just queue up the F8s. I open the console, start the machine, activate the console and then just keep pressing F8 until the keyboard buffer overflow beeps.

That seems obvious, but the problem is the console is not accepting/passing along the F8 keystrokes in time to pass along to the booting system.

Hi

You need to delay the boot to give you the time to press F8.

1º You can do this by script: Check here an example:
http://jeffwouters.nl/index.php/2011/08/powershell-script-to-set-startup-delay-on-virtual-machines-in-hyper-v/

2º Or you can change the settings to delay boot. Check here:

Hope this can help

Nope... that just delays the start of boot. It doesn't affect how quickly access is provided to the console after the boot starts. We are accessing the Hyper-V Host from a management console running on another Hyper-V Host. For whatever reason, probably because the guest SBS that won't start was the domain controller, the management console was taking too long to negotiate access to the remote guest we were trying to start. So, we copied the guest VHDs to the same Hyper-V host where the management console was located and mounted from that server. With everything local, we were able to boot the guest and effectively press F8 and get into safemode. After fixing the problem, which was an AVG / Windows Update compatibility problem, we moved the guest VHD back to it's original host and all is well. But thanks for everyones input.

We would have identified the cause of the problem as delays caused by remote access if the asker had included that fact.

Please accept our apologies. But understand that we didn't know that remote access was the cause. That's the solution we were looking for from this group. If remote access is a know problem related to gaining F8 access, why didn't anyone, "Are you using remote access?" I sure couldn't find anything like that in general searches. We stumbled upon the solution trying anything we could think of to get this clients server back online and felt we should share it.
