@JasGot said in Hyper-V 2012R2 unable to add boot device:
@JaredBusch Is the VM Gen1 or Gen2?
Look on the Summary tab at the bottom of Hyper-V Manager when the VM Server is highlighted.
You can easily see it's Gen2 by the settings window in his screenshot.
-
@Obsolesce Where? Can you circle it?

Go create a gen1 VM, look at the settings, then look at Jared's screenshot. It'll be 1000% clear.

Does deleting the DVD drive, applying that, then adding it again get it listed?
It did not add it to the list.
But when I first click New DVD drive, the Firmware changes to say boot entry changes pending.
but nothing is changed in the end.
-
@JaredBusch Can you add an additional SCSI Controller and then add the DVD Drive to that new controller on the VM?

I'll try it when the restore finishes.

Very weird.
Do you have enough free space to duplicate the disk and attach it to a new VM? Not sure if that'll work, might be worth testing with a test VM and disk with same OS.

No luck.

@JaredBusch clicking "apply" after adding the boot device should commit those changes. I click apply after each setting I change on any VM.

Not at the moment. In a couple months, after they move from Exchange 2013 on prem to Exchange Online I will have all the space I need for workload changes.
But a couple months does not help me know. I was hoping ot boot to gparted to see what is says about the underlying disk (see my other thread).

Yes, new device, change, wtf ever all apply, but there is never anything added to the boot order.

I'll be spinning up a new Nextcloud instance and simply manually migrating users to it I think.
