This question has been asked plenty, but none of them resolve the issue for me.
I have a hypervisor (Hyper-V 2012). When I go to add a new VM from this .iso, which is the Microsoft SQL Server 2012 Evaluation.
When I create a new VM, and make it a Generation 2, then start it, I get this error:
Here's what I've tried.
Pressing a key to retry the boot sequence... (same results)
Retrying as Generation 1 (gave me an error which meant it wanted to be Gen 2)
Downloaded the ISO again to make sure there were no issues with that, and rebuilding.
Unchecking Secure Boot in the Hyper-V Bios settings.
Several places said to hold down any key during boot, and before boot, and that didn't do anything.
Used restroom, to see if a solution came to me. It didn't.
It turns out the ISO that I downloaded twice, wasn't the actual OS ISO. I thought that MS was still releasing SQL ISO's, but apparently you have to download the core OS ISO, and later add the SQL ISO. After getting the core OS ISO, everything worked fine.
