This eror code always appears when i try to start the virtual machine
Hey, I am not quite sure what this error means. However, I have found the following during a quick google search.
It seems that you installed VirtualBox on a drive different from the C:\ drive. This apparently causes problems. You could try reinstalling VirtualBox using the official installer without changing the suggested installation directory, or, if you absolutely must change it, at least specify one that is located on the C:\ drive. Note also that if you chose to change the installation directory due to space restrictions, a VirtualBox installation only requires less than 300 MB (according to the linked post) and you can store the additional data, such as iso images etc. separately e.g. on your D:\ drive.
Hope this helps.
worked out perfectly thank you!
