I am running Hortonworks Data Platform (HDP®) 2.6.4 on Hortonworks Sandbox in VirtualBox 5.2.8 on Windows 10. The virtual machine boots up and seems to get stuck for several minutes on: Waiting for ambari services to start...........
After waiting maybe 10 minutes, the console turns black/empty, the installation does not complete and I do not see the confirmation screen.
Any help to get past this is much appreciated.

With the help of a very experienced hadoop user, I got my sandbox running in VirtualBox with the following steps:
(1) In Ambari, saw that NameNode was not starting up correctly:
* Click on "ops" link to the right of "Sandbox" on top of page
* Click on "Start HDFS" link in "Background Operations Running list
* Click on "sandbox-hdp.hortonworks.com" link
* Click on "NameNode Start" link to see log:
2018-03-13 21:49:05,396 - Waiting up to 19 minutes for the NameNode to leave Safemode...
2018-03-13 21:49:05,397 - Execute['/usr/hdp/current/hadoop-hdfs-namenode/bin/hdfs dfsadmin -fs hdfs://sandbox-hdp.hortonworks.com:8020 -safemode get | grep 'Safe mode is OFF''] {'logoutput': True, 'tries': 115, 'user': 'hdfs', 'try_sleep': 10}

(2) Using putty, ssh to 127.0.0.1 port 2222 log in as root and run:
[root@sandbox-hdp ~]# sudo -u hdfs hadoop dfsadmin -safemode leave
Safe mode is OFF
(3) In Ambari Dashboard on bottom left, in Actions menu, restart all services by:
* Click "Stop All" link and wait until completed
* Click "Start All" link and wait until completed

1. When you see a black/empty VM splash page, try pressing the "CTRL" key.
2. I've successfully ran on VirtualBox 5.2.6. I will upgrade to VirtualBox 5.2.8 and re-deploy.
3. On your browser, try connecting to localhost:4200, localhost:8080 and localhost:8888 - do they connect successfully?
