  1. May 29, 2019  You would setup your user account, but I would not copy back all your data onto the SSD at that point. I would instead run Boot Camp and let it partition the disk first and then when that is done, you can run the Migration Assistant app to copy back the data you have in Time Machine or the clone disk.
  2. Apr 06, 2020 Choose Apple menu System Preferences, then click Startup Disk. Click the lock and enter your administrator password. Select your startup disk, then restart your Mac. If you see a message that your security settings do not allow this Mac to use an external startup disk, check the External Boot setting in Startup Security Utility.

Boot Camp will add a partition on-the-fly to your system drive, but there are some things that can stand in the way of that process. AppleInsider explains how to fix most of the issues preventing you from setting up that partition, if the assistant throws you the failure to partition error.

Pre-step. Get a backup with something other than Time Machine. For this task, we recommend Carbon Copy Cloner, SuperDuper, or ChronoSync to make a fully bootable, fully clone-able backup volume.
We've spoken about Carbon Copy Cloner and ChronoSync in the past. Before we go any further, it might be worth taking a look again.

Disable FileVault

FileVault can, in some cases interfere with the partitioning process. Why, we're not sure, but the best and least destructive, way around it is to turn off Filevault, if it is on. If it isn't, then go to the next step.
Select System Preferences, and click Security and Privacy.

Click on the FileVault tab. Unlock the pane, validate your credentials, and click Turn Off FileVault.

This isn't an immediate process. Decryption of your drive happens when the Mac is awake and plugged in. So, either use your Mac for a few hours doing things other than making a Boot Camp partition, or tell your Mac to never sleep in the Energy Saver control panel and walk away for a while.

Turn off Time Machine, un-associate any backup drives

You've got a backup, right? Don't proceed any further unless you have a backup that doesn't depend on Time Machine.
First, disassociate any backup drives with Time Machine. Select System Preferences, and click Time Machine.

Click Select Disk

Mac Partition Disk

Click on the drive being used as your Time Machine backup, and click Remove Disk. The Mac will pop up a dialog asking you to confirm that you want to do so.

Try to use Boot Camp assistant to partition the drive again. Should it still fail, you may need to remove Time Machine local snapshots as well.

Purge Time Machine local snapshots

For the tech saavy, the procedure to do this is different in High Sierra than it used to be. Apple killed a one-step, easy, Terminal process to turn off the feature, and automatically delete all local snapshots.
The procedure is still in the Terminal, though. Open the Terminal.

Enter tmutil thinlocalsnapshots / 9999999999999999
Depending on how many you have, and the speed of your drive, it may take a few moments to eradicate all the snapshots.

The above steps deal with most of the obstacles to a successful Boot Camp Assistant partitioning of your system drive. Once more, try to use Boot Camp Assistant to make the partition.
If all that still doesn't allow the partition to be created, then..

Format your hard drive

If you've gotten this far, we're pretty confident of your ability to do this step. First, make sure you have a backup! Reformat your drive either by booting from your restore clone, or rebooting in recovery mode, and set up an APFS partition for your macOS install, and a
