Sadly, we don’t test against Hyper V. It has had no end of issues with CentOS and Linux in general. I realise that some people are required to use HyperV, but it’s not something we officially support.
However, unofficially, it’s pretty easy to get some debugging as to why it’s crashing. When you’re at the GRUB screen:
Hit ‘e’ to edit the kernel arguments, and then select the kernel line and hit ‘e’ again. You want to remove the ‘quiet’ from the end of that line.
Hit enter, and then b, and it’ll boot up with much more information, and you’ll see WHY it’s crashing.
(If you don’t get enough, reboot again and remove ‘rhgb’ as well)
