Mac Os X Virtual Machine Boot Camp

With Fusion, you can run Windows from a Boot Camp partition, install from a Windows disc, migrate from an existing PC or even install macOS as a virtual machine from the recovery partition. Fusion provides a simple yet customizable way to install multiple operating systems on your Mac. Give your new virtual machine a name (I just called it “Mac OS X”) and set the operating system to “Mac OS X Server (64-bit)“. Advertisement Click Next and choose how much RAM to give your.

Hello and welcome to my User Tip



I wrote this because we get a lot of questions what would be the best way to run Windows on a Mac.




If one PC program or so, you can check if it will run well in the program called Wine, but it might be a hassle and problematic.


If one PC program or so, you can check if it will run fine in the program called Codeweavers, but it might be a hassle and problematic.


You can run a paid commercial virtual machine program (Parallels or VMFusion) that runs Windows/Linux and some OS X versions in a window in OS X, the updates are paid some are more frequent, but it gives more features (copy BootCamp partition to use as a vm for instance) and ease to install. Easy to revert to earlier snapshots of the guest OS. Have to purchase a copy of Windows.


You can run a free virtual machine program (VirtualBox) which will do the job like the commercial ones do (revert snapshots too), but isn't as feature rich, but it is supported in older OS X versions a lot longer than the commercial versions and it is free, so it only nags to update.


You can run Windows in Apple's BootCamp, which partitions the boot drive and you install Windows in there, which gives the best hardware performance as one directly boots into Windows, but you can't use Windows System Restore or other disk/backup utilities but there is WinClone which clones it from OS X to restore later.



Mac Os X Virtual Machine Boot Camp


BootCamp - Pro's


Full access to the hardware for 3D games and heavier CPU needs


Can run on less powerful Mac hardware


Free, included with all new Mac's.


Easy Mac like setup for BootCamp partition



BootCamp - Con's


More 'geekier' requires more computer knowledge and skills.


Have to boot into OS X or Windows at start time by holding the option key down (to switch if other is set to start first)


Get's malware like a PC, hard to eradicate, may affect OS X


Have to use WinClone to make backups


Have to keep OS X partition on the drive for updates, firmware, repairs.


Harder to fix and repair than a generic PC which third party Windows software designed for


Only supports Windows 7 (recent OS X version supports Windows 8 also.)


Issues with partitioning with bad sectors and/or data on the lower part of the drive





There are plenty of videos on YouTube showing the install method too.



Backing up BootCamped Windows: For cloning/backing up Windows in BootCamp, search for 'WinClone' on MacUpdate.com, runs in OS X.



BootCamp issues:


For bad sector issues and failing to partition: on hard drives, (SSD's not affected). Quit Bootcamp and use Disk Utility from the OS X install Disk or via Recovery HD (hold command r at boot) to Repair the drive two times to make sure.


Then reboot normally and then use Disk Utitity > Erase Free Space > Zero option (not Erase w/Security Option > Zero) and on 10.7 or later 'Zero' in Disk Utility is the slider selection #2 (one space to the right) and make sure it's Erase FREE space only on the Macintosh HD partition only.


Once that's finished, quit and try partitioning BootCamp in the BootCamp Utility again.



Can't parititon/move files issue: For data on the lower part of the hard drive (not SSD's) that inhibits the creation/size of the BootCamp partition, requires backing up User data, cloning OS X partition off to a external drive, erasing the OS X internal drive partition of data and reverse cloning the OS X data back on.







Virtual Machine software - Pro's


Runs guest OS in a window on OS X, more friendly to new users and those not sure yet.


Easy to switch from OS X to Windows to Linux back and forth, as many operating systems as your RAM can support.


Commercial versions of VM software can copy presently installed BootCamp and use that Windows in OS X for best of both BootCamp AND virtual machine versions.


Easier to use, 'snapshots' of Guest OS state can be reverted back to in seconds for updates/malware issues.


Runs most any OS version, Windows XP, Vista, 7, 8, Linux's, OS X Server editions only (VMed Lion in Lion, ok)


Run more than one Guest OS at a time with enough RAM and drive space


Easier to use for most lightweight guest OS programs, no need to dual boot, run guest OS like a file in a program.


Some integration possibilities, copy and paste, shared folders etc between the two or more OS's


Easier to get out of trouble via the virtual machine software or OS X 'Force Quit'



Virtual Machine software - Con's


Guest OS doesn't have access to the hardware, no Direct X, 3D animation limited /slowed apx 1/5th speed as native boot, really only shows on 3D games etc.


Requires more RAM, more powerful machine: 4+ cores, 4GB+ RAM, dedicated video card preferred. (2 cores 2GB RAM possible but not recommended)


Have to share RAM and cores with OS X


Can't run OS X client versions (except Lion in Lion) as Apple asked them not too.




Note: I scaled the virtual machines windows down for effect, they can be full size or larger

If you own Intel-based Macs, you can run OS X and Windows on one machine. In fact, it’s been possible to run Windows on a Mac for some time — with agonizing limitations. Near-extinct Mac models were loaded with Virtual PC emulation software could do Windows, too, but the program was painfully slow. Even if you find an old copy of the software, it won’t work with any current Macs.

Boot Camp software from Apple shook up the computing public upon its apocalyptic arrival in April 2006. Boot Camp graduated from beta, or near-finished, status with the arrival of Leopard. Boot Camp Assistant software is stored in the Utilities folder inside the Applications folder.

Boot Camp itself is free. You have to supply your own single-disc or downloadable full-install version of Windows; an upgrade disc won’t cut it.

It’s also important to note that you can use a 64-bit version of Windows, Windows 7 (Home Premium, Professional, or Ultimate), Windows 8, or Windows 8.1. Consult Apple support to see which Mac models are compatible with which versions of Windows. In its current incarnation, Boot Camp isn’t compatible with 32-bit versions of Windows.

Other requirements follow:

  • An Intel Mac with OS X version 10.6 or later

  • At least 2GB of RAM and 20GB of available space on the Mac’s storage drive that you want to donate to Windows

  • A blank CD or USB storage device that you’ll use for Windows software drivers

If you don’t run into snags, the entire installation should take about an hour.

Windows 8 and Windows 8.1 are optimized for a touchscreen environment, though you can use it with a standard mouse and keyboard. For now, Macs don’t support touchscreen computing.

To install Windows 8 via Boot Camp, you still must have a legitimate Windows 8 license from Microsoft and a Win8 installation disc, assuming that you have an optical drive. If you don’t have an optical drive, you may be able to create a Windows installer from an ISO file downloaded from Microsoft on a USB flash drive that’s 8GB or larger.

Because snags are possible, back up all your important information on the Mac’s startup disk.

Basic training

Following are the basic steps to get through Boot Camp:

  1. Run Boot Camp Assistant (in the Utilities folder inside the Applications folder) to make sure that you have the latest firmware on your computer and to install any support software from Apple that you might need.

    You’ll find any updates at Apple support. If you’re using a portable computer, make sure to connect the power adapter. You will also be given the option to create a Windows 7 (or later version) install disk for which you’ll need a USB flash drive and an ISO image downloaded from Apple.

  2. Follow the prompts in Boot Camp Assistant to create a partition for Windows.

    You’re essentially carving out an area of your hard drive for the Windows operating system,. This partition must be at least 30GB and can swell to the total free disk space on hand minus 30GB. If you don’t plan on doing much in Windows, keep the partition small.

    Drag the divider to set the partitions for both OS X and Windows, or click Divide Equally to make equal partitions. You can’t resize a Windows partition after creating it, though you can replace it with a larger Windows partition.

    If you have a Mac Pro with more than one internal hard drive, you can select which drive to partition. If any of this makes you nervous, know that you can remove the Windows partition later and go back to a single-partition Mac.

  3. Insert the Windows CD or a USB flash drive with the Windows ISO file and then click Start Installation.

    If you exited Boot Camp Assistant before installing Windows, open it again, choose Start the Windows Installer, and click Continue.

  4. When you’re asked to choose the Windows partition, select the partition that says BOOTCAMP.

    You may have to scroll down to see it.

    Don’t erase any partitions that you see or create a new partition here. Failure to heed this warning could wipe out your entire Mac OS X startup disk.

  5. (Optional) If you see a listing for Drive Options, click it; otherwise, proceed to Step 6.

  6. Reformat the partition by using the Windows installer: Click Format.

    You’re using the reliable and secure NTFS file system, but you won’t be able to save files to Windows from Mac OS X, at least not without a techie workaround.

  7. Follow the onscreen instructions to finish installing Windows.

    Boot Camp 5.1 includes several Mac drivers so that Windows will recognize your trackpad, Thunderbolt, USB 3.0, the iSight (or FaceTime) camera, the Eject key on the Mac keyboard, networking, audio, graphics, and so on.

    A Boot Camp Control Panel for Windows and an Apple Boot Camp system-tray item will be added.

As with any new Windows computer, Microsoft requires that you activate your Windows software within 30 days.

Switching operating systems

You can go back and forth between OS X and Windows on your Mac, but you can’t run both operating systems simultaneously under Boot Camp. Instead, you have to boot one operating system or the other — thus, the name Boot Camp.

Mac Os X Virtual Machine Boot Camp 2017

Restart your Mac, and hold down the Option key until icons for each operating system appear onscreen. Highlight Windows or Macintosh HD, and click the arrow to launch the operating system of choice for this session.

If you want OS X or Windows to boot every time, choose app → System Preferences, click Startup Disk, and choose the OS you want to launch by default.

You can perform the same function in Windows by clicking the Boot Camp system-tray icon and selecting the Boot Camp Control Panel. Click either the Macintosh HD or Windows icon, depending on your startup preference.
