Dual boot mac windows separate hard drives

More is better, but remember, the more you give Windows, the less you'll have for macOS when you're running both in tandem, so try to strike a balance.

What You'll Need

As long as you stay within the green bar for RAM and choose a Dynamically Allocated disk, you should have enough leeway. Once installed, select the virtual machine in the sidebar and click the "Settings" button in the toolbar. But in order to install Windows, you'll need to go to the Storage tab and load the ISO you downloaded earlier. Click OK when done.

Now click the big green Start button in the toolbar, and you're off to the races. VirtualBox will launch the Windows installer, and you can set it up just as if it were on a new PC. Your virtual hard disk will be empty, so you'll have to choose "Custom Install" when prompted, and select your hard drive and click "New" to format it. This will give you shared folders, better video support, and other handy integrations. You'll even be able to run applications in their own window on your Mac desktop using Seamless Mode, accessible from VirtualBox's "View" menu.

If you like the idea of virtualizing Windows but VirtualBox feels a bit too technical, or you want more features—like the ability to virtualize your Boot Camp partition —Parallels is a fantastic way to run Windows on your Mac. Install it on your Mac, and start it up.

If you already have a Boot Camp partition, it'll ask if you want to use that as your Windows installation. If not, you can just click the "Install Windows" button, and Parallels will do all the heavy lifting for you—downloading, installing, and preparing Windows. Just sit back, grab a cup of coffee, and in a little while, you'll be dumped onto the Windows desktop. You'll have to create a Parallels account in order to use the virtual machine, but once you've done so, you can click around Windows, install programs, and use it as normal.

You can adjust Parallels' resource allocation in its settings if you feel Windows needs more RAM or CPU than Parallels has provided , or click on its menu bar icon to enter "Coherence Mode," where you can launch Windows apps in their own window on your Mac desktop. When it comes to ease of use, Parallels is definitely worth the money.

After I boot Windows after clover, the bios registers have changed, the Windows boot loader is back and has been moved to the top of the list. This does not happen in any of my other hacks, so I believe this has something to do with the bios management of the optiplex.

Which is the reason why this was initially posted in the Dell forum. I will try moving them around and see what happens. First link. If nothing is shown in red with error messages when you highlight them you probably have a disk with a standard CHS partition table alignment. If you wish to edit the partition table with Linux, first run sfdisk with "--show-geometry" and "--show-pt-geometry". If you add a partition to the middle of the extended partition table, GParted will not put them in the order they are on the disk so that hda7 will follow hda9 instead of hda6.

The order can be fixed with a Linux fdisk advanced function. Most Linux partitioners that don't use parted , may not end EBR extended partitions type 05 on the same sector as their logical drives. When GParted or parted edit these "nonstandard" partition tables, they will "fix" all these EBRs, so that the extended partitions end on the same sector as their logical drives. The partitioner then may show these partitions as having no "errors". One popular multi-boot configuration is to dual-boot Linux and Windows operating systems, each contained within its own partition.

Windows does not facilitate or support multi-boot systems, other than allowing for partition-specific installations, and no choice of boot loader is offered. However, most current Linux installers accommodate dual-booting although some knowledge of partitions is desirable.


Commonly installations proceed without incident but upon restart, the boot loader will recognize only one of the two operating systems. Windows operating systems will be found by properly installed Linux bootloaders, but Windows boot managers do not recognize Linux installations nor does Windows deal natively with Linux file systems. However, in Vista, in order to install services packs or other Windows updates it may be necessary to restore the Vista boot loader first.

Similar problems may occur with SP1 [4] or when there are cloned disks or partitions. It is often recommended that Windows be installed to the first primary partition. The boot loaders of both Windows and Linux identify partitions with a number derived by counting the partitions. Note, both Windows and Linux count the partitions according to the ordering of the partitions in the partition table , which may be different from the order of the partitions on the disk.

Adding or deleting a partition at the end of a hard drive will have no effect on any partitions prior to it.

However, if a partition is added or deleted at the beginning or middle of a hard drive, the numbering of subsequent partitions may change. If the number of the system partition changes, it requires boot loader reconfiguration in order for an operating system to boot and function properly. Windows must be installed into a primary partition and in older systems this must be the first partition. Linux can be installed into a partition in any position on the hard drive and can also be installed into logical partitions within the extended partition.

If Linux is installed into a logical partition within the extended partition , it is unaffected by changes in the primary partitions. With the boot flag set on the Windows primary, the Windows Boot Manager can be used to chainload another installed bootloader by employing usage of a program like EasyBCD. The software comes bundled with Mac OS X since version Previously the application was available in beta version as a download from Apple's website.

Apple does not support non-Windows partition formats or drivers so therefore configuring other operating systems is not directly possible through Boot Camp itself. The Ubuntu Linux distribution is particularly popular for this purpose because they provide an option to use proprietary device drivers along with open source drivers.
