I have several fully patched Windows 2016, 2019, and Windows 10 machines that will not boot after upgrading compatibility to ESXi 7.0 U2 version 19. They will just hang at the blue windows logo screen forever.
These machines do have VBS enabled but it doesn't matter if I turn it off before or after upgrading compatibility, it won't boot after either way. Other VMs that didn't have that set seem to upgrade fine.
So far I have to restore a snapshot to get the VMs working again. Any ideas how to fix this?
It had the exact same issue. VM stuck at Windows boot logo. Could successfully solve this problem by manually editing the vmx file and changing virtual hardware version from 19 (18 on a different VM) both to 17. Unregistering VM and re-registering with "new" vmx-file let my VM's boot correctly. Hope this helps.. good luck.
