I must have missed something and somebody might know what Eventually needed to try Windows8-ReleasePreview-64bit-English in VMware Workstation Technology Preview 2012 (nothing moded for this exercise, just in case) Using default settings (hardware compatibility Workstation 2012, Windows 8 64-bit) it installs fine from iso, but never boots after that (stays on the Windows black logo) Changing the hardware compatibility to Workstation 8 makes it work OK (but I can never login to it, it just spins around) Then renaming vmware-vmx.exe to vmware-vmx-debug.exe (so I do not get the debug warning) I am back to the same as originally, it does not load & stays on the Windows black logo Anybody having any idea? Edit: Reinstalled it 4 times (as Workstation 8/Win7 x64) and eventually works sebus
