I faintly remember that you can't as bootcamp partition is the system/boot partition for Windows and Windows disk management does not allow expanding of system/boot partition. I don't think gparted can be a solution too since it doesn't boot on mac.

  1. Mar 16, 2018  Access Mac HFS+ Partitions From Windows. RELATED: How to Install Windows on a Mac With Boot Camp Apple’s Boot Camp driver package automatically installs an HFS+ driver for Windows, which allows Windows to see your Mac partition. This partition shows up as “Macintosh HD” under Computer on your Windows system. There’s a big limitation here, though — the driver is read-only.

So windows is GONE. I think I am more sad about the 250 gigs of games I had. It just takes so long to download each one in steam. Best, Joshua.

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


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 macOS Extended (journaled) partition for what will become your Boot Camp partition later in the process.
Restore your backup to the APFS partition, run the Boot Camp Assistant again, and all should be well.

Boot Camp is an application from Apple Inc that helps in installing Microsoft Windows operating system on your Intel based Mac. With this multi-boot utility, you can install and use any Windows OS along side your Mac operating system. Once finished configuring the Boot Camp Assistant, you can boot your Mac, choose between Mac and Windows OS and use features of both the OS. In fact, Boot Camp has provided Mac users the opportunity to use essential Windows programs, without having another Windows-only system.

Though Boot Camp is a wonderful idea to consolidate PCs into the world of Mac, its implementation is not a trivial task. The process simply involves creation of a new partition by repartitioning the Mac hard drive and installation of Windows OS as well as various device drivers. Below steps will give you a clear picture on how to install Windows on Mac by creating a Boot Camp partition.

Steps to Install Windows by Creating Boot Camp Partition on Mac:

  • Launch Boot Camp Assistant from /Applications/Utilities/
    Note: Before starting up the process, it is advised to backup all important data and log in as administrator to quit all running applications.
  • Adjust the divider to create a Windows partition of the required size. You can click the ‘Divide Equally’ button to divide the entire Mac hard drive into two equal pieces. You can also click the ‘Use 32 GB’ button to create a Windows partition of exactly 32 GB. Click on ‘Partition’ button.
  • The Windows partition gets created. Insert your Windows installation disk and click the button, ‘Start Installation’ in Boot Camp Assistant.
  • Select the partition named ‘C:Partition 3’. Note that in Vista select ‘Disk 0 Partition 3 BOOTCAMP’.
    Caution: Be careful in choosing only the above mentioned partition, or else you will end up erasing data from your Mac partition.
  • Complete the Windows installation process and insert your Mac OS X installation disc to install the drivers. Restart your Mac.
