The trick to a fairly quick and easy installation is some preparation ahead of time. I have been fortunate recently in getting a couple of extra desktop computers. So I have been playing around with installing and trying other distros. But I have always ended up coming back to Zorin for my daily use. I can install Zorin 16 core in about an hour.
As Aravsian posted it takes about 30 to 35 minutes for the operating system to install if you install it as dual boot on a regular HD. Then I install Brave as my browser and after it is installed I then use the sync function to copy my favorites and passwords to the new PC. I then may or may not install my email client depending on what I am planning to do with the PC. But even if I install my email I can still be done with the basics in about an hour.
Of course if there are other programs I want to install other than what already comes installed then it will take some more time to install them. But most of what I use is already installed in the core version of Zorin.
If you install Zorin as dual boot with Windows, Zorin makes it easy to access the files you have on the Windows side. But of course you should always make a back up of any files you don't want to lose before doing anything.

. How long it already takes to do all the updates, reboot, update, reboot, update...installing, reboot, almost there, oh wait...the user likes those reboots after each update lets reboot again, nvidia driver installed lets reboot, realtek hd audio driver installed ... You guessed it ... Reboot.
