Mojave guest OS on Yosemite Host via Parallels Desktop 10 I can't get to the welcome choose your country screen when installing Mojave virtualised via Parallels Desktop 10 on my Yosemite system (MBP Retina 2015). 

I downloaded the 6GB Mojave '.app' file as per the OSX Daily webpage (http://osxdaily.com/2018/09/29/download-full-macos-mojave-installer/) via the installer from this website:
http://dosdude1.com/mojave/

1st attempt (via .app file):
Parallels didn't automatically find the OS file so I located manually. I got the message "unable to detect operating system". I clicked continue and selected OSX. When starting up I got a boot failed message. I figured perhaps Parallels doesn't recognise an OS via .app file and that I should convert it into an ISO file...

2nd attempt (via ISO file):
I created an ISO file from the .app file. I did this via steps 1-7 (under the 'Creating the installation media image iso' sub-heading)in this link: https://www.reddit.com/r/hackintosh/comments/a9twye/mac_os_1014_mojave_vmware_15_diy_guide_no_3rd/

Again Parallels didn't automatically find the OS file so I located manually. I got the message "unable to detect operating system". I clicked continue and selected OSX. This time I got the apple logo and load-up bar screen. I then got the MacOS Utility screen. After selecting 'install macOS'  and clicking continue it took several minutes to get to the next page. Then I got to the screen where It says select your drive to install. I selected the Macintosh HD and clicked next but then I got the error message:
"An internal error occurred while preflighting your volume for APFS conversion".
I was reverted back to the MacOS Utility screen. So this time I did not click on 'Install MacOS' instead I selected 'Disk Utility' and clicked continue which quickly took me to the Disk Utility screen. I selected the Macintosh HD and went on the menu bar to select [Edit -> convert to APFS...]. I got the dialog box 'Converting Macintosh HD to APFS' saying the conversion was complete and the operation was successful.

So now I got past the select your drive to install screen. However, I couldn't complete the installation. Using this video as a reference (https://www.youtube.com/watch?v=QbLEtH4PnlQ):
I couldn't get past the blue loading-bar screen (6:00) ie. could not reach the welcome screen (6:03). Basically after the blue loading-bar screen I get the initial apple logo screen and then goes back to the MacOS Utility screen.

I don't know if this is an issue with Parallels Desktop 10, the Mojave file I downloaded or something related to compatibility. I prefer not to update/upgrade Yosemite.

Would greatly appreciate any advice.
Here are the visualizers that I know about.

VirtualBox
VirtualBox is free, but you get what you pay for. Works fine for non-macOS operating systems.  Nightmare to get to work for macOS.  Basically, you need to match a version of VirtualBox with a version of macOS that will work.
