This is solution for Gen2 i found on a forum
"Press 'reset' in the tool bar when you have this error and then press space as the machine resets. You have to be quick, it will then boot from the ISO image. This issue has been there for a few years now, and I'm surprised it's not fixed"

Thank you so much David for the quick fix. This was smooth.

TYSM! I was racking my brain trying to figure this out myself. I never considered if it was something simple.

Where did you get that 'Windows 10 Pro.iso' file you used?

Thanks, David, you're a lifesaver :-)

I was just "no.. another video where the solution is to re-do everything..." But no, this actually fixed it for me.

I did a vhd file (converted a physical machine) with the latest version of the conversion tool, and then I selected hardware version 2, I though that was the correct way... but noup. looks like the vhd still being created in v1. THANKS

Wow. Thank you so much, David. It worked.

Thank you - that helped a lot. I was using the Quick Create and trying for WinXP 32 SP3 :)

[SheffieldJourno]

Awesome, thanks! It was the wrong generation setting for me that caused it.

Many Thanks Converting from VM-Ware to Hyper- v Had that issue was the generation selected🙂. Saved me a lot of work

What zaygum khan said. Easy, quick, straight to the point. <3 Thanks so much!

I had tried using the Quick Create option, which gave me the error. Then I tried using Gen 1, which also gave me the error. Then, I did Gen 2 and it's working great! Thanks for the help. How do you know which version your iso is, though? I didn't see any obvious signs it would be one or the other.

i am installing windows 7 in generation 2 for UEFI, it's being install as well but after restarting that same error is how can i resolve it.

[juancarlosbeltran]

[dqtlfyg]

thx david this was the best video for hyper

[fernandoassis]

Thank you so much! You help me to save several time!

Your video helped me resolve my problem. I always press the 'Quick Create' button, and I encounter this issue. However, when I follow your steps, my virtual machine successfully loads.
