As Microsoft is continuously updating their technical preview for Windows 10, we are sure many of you out there are trying out the latest release 10074, that adds(?) many features. As a precaution, we always use Oracle VirtualBox for testing such releases and never had more issues than with the pre-releases of Windows 10!
One of the regular errors we came across were about “Unable to allocate and lock memory” while the VM started, and gradually pops up another window titled “Guru Meditation”, asking us to view the log files (/me chuckles, when Google can do that for us). We came across a wonderful post, that explains how to resolve this particular dreadful situation with VMs!
and here we are linking the same POST for you! Enjoy and Enjoy your Windows 10 VM
