My problem is very unique. My VM was working just fine with no issues, but yesterday I removed my VM by clicking on remove. but instead of clicking remove only, i clicked delete all files! My VHD got deleted permanently! So, with muchh patience, I downloaded it again(7.39 GB)..but this time, something strange happened. WHen I started it, a screen started and I can give you one word that was showing a lot and it is ""removing orphan file""...something like that...and it took approx 1/2 hour and when it was done, i tried to start the VM and now there was an error...and the error was..""lsass.exe system error: Security Accounts Manager initialization failed because Directory Service cannot start"". Than I tried formatting my C drive. Installed everything again and now the error is gone, but got new strange issue! BLACK screen....nothing happens! Please help me guys... I lost my sleep over this.. My Host OS is WIndows 7 and Guest OS is Windows Server 2003. Thank you" defect closed host support VirtualBox 5.2.12 invalid Windows Windows
