I tried to install Windows 8 at my vSphere 5 patch 1 environment, but after starting the VM I received a warning:
Your computer ran into a problem and needs to restart.
If you’d like to know more, you can search online later for this code: HAL_INITIALIZATION_FAILED
It’s collecting error info and will restart in: 0 seconds
Only you have to do is add the new guest OS in you’re .vmx file, re-add the file to your vSphere inventory and start the VM. Guest OS you need to add:
guestOS = "windows8srv-32"
guestOS = "windows8srv-64"
Note: if you’re running vSphere 5 without Update 1 you need to install Patch 02
– The installation will start, have fun!
