Hi, ChimairaUK.
For the future, please make different posts for each topic as the troubleshooting process can get complicated and confusing with more than one topic.
Also, in general please provide details for any issue.
Specifically,
For the booting - please post a picture of the errors.
For Oracle, did you get the Ubuntu 18.04 package here? https://www.virtualbox.org/wiki/Linux_Downloads - if yes then what are the details of the problem?
